Leaf-footed bugs are a family of plant-eating true bugs known for their unique, leaf-like extensions on their hind legs. These insects can be found feeding on various plants, causing damage to buds, flowers, fruits, and seeds. Interestingly, their ability to fly might not be well-known to those encountering them in their gardens.
These bugs are indeed capable of flying, and they typically create a noisy buzzing sound while doing so. Good flyers, they can easily move from one plant to another, increasing their potential to cause damage to various crops in a short amount of time. Understanding their flying abilities can help gardeners and farmers better manage these pests and take appropriate measures to protect their plants.
Leaf Footed Bugs Overview
Leaf-footed bugs belong to the Coreidae family of true bugs and are named after the unique, flattened, leaf-like extensions found on many species’ hind legs1. These insects are usually dark-colored, with some species showing tan, orange, or yellowish markings:
- 1/2 to 3/4 inch long body
- Well-developed wings
- Distinctive leaf-shaped hind leg extensions2
- Variations in color and markings
Leaf-footed bugs undergo a simple metamorphosis:
- Eggs are laid on plant stems and leaves
- Nymphs hatch, resembling smaller, wingless adults
- Nymphs molt multiple times before reaching adulthood
The nymphs are often deep orange or light brown in color and lack the “leaf-footed” extensions seen on adults3.
Habitat and Distribution
These true bugs are commonly found in North America, and they inhabit a range of environments. Some important aspects of their habitat and distribution include:
- Primarily distributed throughout North America4
- Living in various environments, including gardens
- Feeding on many different plants, damaging buds, flowers, fruits, and seeds5
Do Leaf Footed Bugs Fly
Leaf-footed bugs can indeed fly. They are good flyers and are capable of making a noisy buzzing sound as they take flight. These flying insects — especially adults — rely on their wings and hind legs for movement. Some of their hind legs possess leaf-like extensions, which is why they’re called leaf-footed bugs.
Seasonal Changes in Habits
Leaf-footed bugs may show changes in their habits depending on the season. During warmer periods, they tend to be more mobile and actively look for food. With increased flying, they make use of their wings and ability to create a buzzing sound. However, when temperatures drop, these insects may adopt less active behaviors and restrict their flying.
- In spring and summer, leaf-footed bugs may be seen frequently flying around in search of food sources.
- Good flyers
- Create a buzzing sound while flying
- Hind legs with leaf-like extensions (in some species)
- Active flying during warmer seasons
- Reduced flying in colder temperatures
Impact on Gardens and Crops
Common Target Plants
Leaf-footed bugs target a variety of plants in gardens and crops, including:
- Fruits, such as citrus
- Nuts, like pistachios and almonds
- Ornamental plants
- Vegetables, including tomatoes and squash
- Trees, such as palm trees, conifer trees, and Joshua trees
Damage to Shoots and Fruits
Leaf-footed bugs cause damage to plants by sucking nutrients from the leaves, shoots, fruits, and seeds. In particular, they have significant effects on fruits such as pomegranates, watermelons, and tomatoes. Their feeding can result in:
- Premature fruit drop
- Discoloration of fruit
- Hardened, yellow spots on fruit
|Leaf-footed Bugs||Squash Bugs|
|Feed on fruits, nuts, flowers||Mostly feed on squash|
|Belong to Coreidae family||Part of Pentatomidae family|
|Widespread and damage various crops||Specific to squash crops|
Overall, leaf-footed bugs pose threats to both ornamental gardens and various crops. Targeting an array of plants, they impact the health and productivity of numerous plants, including fruits and vegetables. Their damage to leaves, shoots, and fruits can lead to diminished yield and quality for gardeners and crop producers alike.
Managing Leaf Footed Bug Infestations
Different Methods of Control
Leaf footed bugs, known for their leaf-like expansions on their hind legs, can be controlled using various methods. One effective approach is using natural predators, such as assassin bugs and ambush bugs from the reduviidae family. These predators help to eliminate the nymphs and adults of leaf footed bugs.
Pros of natural predators:
Cons of natural predators:
- May not control the entire infestation
- Takes time to see results
Another method for managing leaf footed bugs is the use of pesticides, including neem oil. Please note, though, that excessive use of pesticides may harm beneficial insects as well.
|Method||Effectiveness||Eco-friendliness||Speed of Results|
Implementing preventative measures can help to avoid or reduce leaf footed bug infestations. Some useful steps include:
- Weed control: Regularly remove weeds around your home and garden, as they can serve as host plants for the bugs.
- Debris removal: Clean up debris such as woodpiles, which can provide hiding spots for bugs during their overwintering stage.
- Row covers: Use row covers on your plants, particularly during the early stages of the bugs’ life cycle, to prevent their access to host plants.
- Monitor eggs: Keep an eye out for tan or orange eggs on the undersides of leaves, and remove them before they hatch into nymphs.
Following these preventative measures can help protect your plants from infestations and ensure a healthier garden.
Over the years, our website, whatsthatbug.com has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.
Letter 1 – Leaf Footed Bugs Hatching
Red insect building amber cells
May 9, 2010
Can you please identify these red insects that are building these amber cells? They’re on my window. They are slow moving; it was very hard to tell if they were alive or not. The body is 3 mm in length x 1mm wide. The amber cells are about 1 mm x 1mm.
These are hatchling Leaf Footed Bugs in the family Coreidae. We are uncertain of the species, but we matched them to a photograph posted to BugGuide.

This was found in the grass under a pine tree. It didn’t fly, just walks. The body is blue with two red dots in the head area. The body curves upward. Stripe legs and antenna. Very tiny, less than dime size. Found June 27th, 2012. Outside temperature in the 90’s that day. We’ve lived here 37 years and never saw one like this ever.

Need confirmation of a bug
June 14, 2010
I did some research, and am about 99% sure that this is a Wheel bug. A young one from what I can tell. I am just hoping you can help me to confirm this. I have been trying to use your website for a few years to help educate my kids to not just smush bugs because they are gross or scary. We have learned a LOT over the last few years, and hope to continue. This was a new one for us, and my husband admitted it was a new one for him. He grew up just a few hours north of where we are (N. Tennessee, right on the TN/KY border) and has never seen one.
This little guy was hanging out on a small rosebush, he was walking around the leaves as if to get a better look at us as we peered at him. He kept extending his front antennae out to us as if inviting us to touch him. After reading about Wheel bugs, I am thankful I did not take him up on his invitation. At one point I pointed at him, and you coulud see him straining to reach my finger. He was a rather interesting guy, and I am glad I took photos when I did, as he has now vanished. I am guessing that there are many more back there, but I read that they are usually quite shy.
At any rate, are we correct?
Sometimes identifying immature True Bugs is difficult because they look so different from the adults. Also, many nymphs from different species look similar. Though your insect resembles the nymph of a Wheel Bug, it belongs to a different family. Your nymph is a Leaf Footed Bug or Big Legged Bug in the family Coreidae. Just last week a similar image was sent to us, and that specimen was identified as a member of the genus Acanthocephala. You can compare your individual to a photo posted to BugGuide. This is our last posting before heading east to Ohio for a week with mom.

Hello, I just started gardening not long ago and I have a mix of squash plants, and tomatoe plants, I noticed that my tomatoe plants has been infested with caterpillars, but now I just saw that there is a new bug that is hanging out on my squash plants. I took a picture and looked these up, I dont know if these are beneficial bugs that eat the caterpillars or the bad bugs that dont..please help. thanks in advance.
In our opinion, these are immature Leaf Footed Bugs in the genus Leptoglossus, based on this BugGuide image. Leaf Footed Bugs feed on the fluids of plants and they might spread virus infections to your crops. You can research some possible species by browsing through BugGuide.

In addition to the predatory Green Lynx Spiders and California Mantids I have living on my pot plants, I now found this impressive guy. So, is this a friend or foe in my garden? Right after I took the photos, it flew away.
How you want your letter signed: Constant Gardener
Dear Constant Gardener,
This big True Bug is one of the Leaf Footed Bugs in the genus Leptoglossus. Based on BugGuide, where it states “Two yellowish spots on the forward part of the pronotum are distinctive. Also has a zigzagging white band across the wings (like some other species). Expansions of the hind tibiae are also much larger and more jagged than most other species.”, it is Leptoglossus zonatus. This is a plant feeding species, and it has a proboscis designed to pierce the plant and suck its juices. BugGuide also states: “Highly polyphagous” which is an indication that if it was on your Cannabis, it was probably feeding.
Letter 6 – Mystery: Unknown Immature Leaf Footed Bug is Acanthocephala species
Blue spiky fiddle bug with red shoes and feelers
June 13, 2010
This bug caught my attention because it was blue and red against white vinyl siding. (Cheering for USA in the World Cup?)
The metal spikes and two blood red eyeballs on its abdomen make for an evil-looking insect, but it looked more lost than anything.
Photos taken at 5:30pm, 11 June 2010.
Maybe he has a bright idea?
Atlanta, Georgia, USA
This is an immature Leaf Footed Bug or Big Legged Bug in the family Coreidae. Often immature insects are difficult to identify to the species level because they change in appearance as they grow. We have located a similar looking, also unidentified nymph on BugGuide, and that specimen was from Louisiana. The person who submitted the photo was raising the nymphs in a terrarium, and there was some serial commentary, but there is no indication that they were ever properly identified.
We have posted a comment on the BugGuide page to inquire if the nymph was ever correctly identified.
Update: Acanthocephala species
We received a comment from lttlechkn question if this might be the nymph of Acanthocephala terminalis. This is a good possibility, but the match to Acanthocephala declivis seems even close, based on a photo, also from Georgia, that is posted to BugGuide.

Dear Lee Yew Moon,
These are not beetles. These look like Leaf Footed Bugs in the family Coreidae to us, but we cannot provide a species name for you. We did find a very similar looking Leaf Footed Bug from Singapore on AllExperts.

Bug on pommegranite

This was a bug I had never noticed before and curious to see them grouped on one fruit and not on the others.
Signature: Martyn Watson
These are immature Leaf Footed Bugs, and we have often found adults of the species Leptoglossus zonatus feeding on pomegranate in Elyria Canyon Park in Los Angeles, but we have not seen the nymphs. We suspect your nymphs are Leptoglossus zonatus. We thought we might be able to verify that on BugGuide, but they do not have any images of the immature stages. Leptoglossus zonatus will also feed on tomatoes. These Leaf Footed Bugs damage the fruit they feed upon by injecting enzymes that cause the flesh to become brown and dry where they pierce the skin. You may see images of the winged adults on BugGuide.

These insects are all over two branches of my pepper plant. They don’t appear to be eating it. What are they? Are they harmful or beneficial to my vegetable garden?
Signature: K. Kelley
Dear K. Kelley,
These are immature Leaf Footed Bugs in the genus Leptoglossus. They look very close to an example, also on a pepper plant, also in Georgia, that was posted to BugGuide. There is a comment on that post that they are not harmful to the plant. It is our observation that a west coast relative in the same genus feeds upon pomegranate and tomatoes, and that the sucking of fluids from the plants, and the probably injection of saliva, causes blemishing on the fruits, so we personally do not consider them to be totally harmless to the plant if there are large numbers of individuals.
Letter 10 – Immature Leaf Footed Bug from Brazil
Red bug from Brazil
February 19, 2011 11:31 am
Hey!! This is a picture from a bug that’s been showing up a lot in my house lately here in Brazil. I’ve seen lots of them around the garden by themselves, but i’ve also spotted them in large groups.
Always wondered what they were, so I thought of asking you!
Oh, and do you know if they are dangerous????
Thanks a lot!!
This is an immature Leaf Footed Bug in the family Coreidae. Leaf Footed Bugs are also known as Big Legged Bugs and Flag Footed Bugs because of the tibiae on the hind legs. Some species, like your individual, have expanded segments on the antennae as well. Because of the distinctive markings on your specimen, we would expect it to be relatively easy to identify the species, however, most sources available identify the adult or imago, and the adult may differ considerably from the young nymph.

What’s the bug on the sunflower?
Location: South Pasadena, CA
May 16, 2011 12:01 am
I have a rogue sunflower in the yard. Today I spotted this bug on it. I thought maybe a leaf-footed bug, which I knew from WTB. I read that sunflowers are popular with leaf-footed bugs. I was sufficiently confident to name the image accordingly, but nowhere near certain.
Hi again Barbara,
We agree that this is an immature Leaf Footed Bug, most likely in the genus Leptoglossus. It is probably the Western Leaf Footed Bug, Leptoglossus clypealis, which may be found on BugGuide. Immature Hemipterans can be quite difficult to identify since many look very similar. BugGuide does not have any images of immature Western Leaf Footed Bugs, however, this image of a nymph from the genus Leptoglossus from Texas posted to BugGuide looks very similar. We have been working for hours this morning on a Powerpoint Presentation for the Theodore Payne Foundation instead of posting new letters. We are hoping you will grant permission to use this image in our presentation.
I’d be pleased to have you use the picture. With some luck, I’ll be able to make your presentation. Thanks for your help with the bug i.d.
I will also be using some of your Monarch Caterpillar images. I have prepared the first half of the presentation and I think it is going to look awesome. Luckily, through the years, many gorgeous images have come to the website thanks to the wonderful talents of the readership. It will be great to meet you face to face if you are able to attend Barbara.
Correction June 17, 2011
Now that Barbara has supplied a photo of the adult, we can correctly identify this as Leptoglossus zonatus.

was in the smoky mountains and spotted this bug. in gatlinburg tn.. what is this
This is an immature Leaf Footed Bug in the family Coreidae, but we do not recognize the species. The metallic blue coloration of the abdomen, red eyes and striped legs are all significant features that might be used for identification. We have found a match on bugGuide from nearby North Carolina, but alas, it is not identified beyond the family level. There was a speculation on that posting that it might be Acanthocephala terminalis, and BugGuide has images of immature individuals that seem to indicate that is a strong possibility. The information page on BugGuide may provide you with additional insight.
Letter 13 – Immature Leaf Footed Bug
Odd bug in Ohio
Location: Ohio, woods near a creek
July 4, 2011 6:46 pm
The bug has three legs and two long antennae, and its eyes are red. The body looks like a V, referring to the wide tail that points upward, and the thorax and head which point up forming a bend, because the junction of the thorax and abdomen is relatively low to the ground. The legs are black with the exception that near the tips they turn white and then orange. The antennae are also black, white, and orange. It seems as though the bug can walk sideways as well as forwards and backwards. I found it on July 4, on my trampoline( probibly doesn’t matter.

I found these guys in my garden on the squash plant. My guess is assasin bug. I’d be happy about that! It would also explain the lack of caterpillars!
In our opinion, these are not Assassin Bug nymphs, but rather Leaf Footed Bug nymphs, probably in the genus Leptoglossus. They look very much like the individuals in this BugGuide image. They are plant feeders and they are not responsible for the dearth of Caterpillars.

Hello bugman! Yesterday morning I found 10 of these bugs walking around one of my tomato cages! I hate exterminating bugs it even pains me when my husband gets rid of ant piles. I belive all animals are important to our ecosystem, I’m really hoping these are Assasin bugs and not Leaf Footed
This sure looks like a Leaf Footed Bug nymph from the genus Leptoglossus to us, based on this image posted to BugGuide. Generally, Assassin Bugs are solitary hunters, and if you find Hemipteran nymphs (not hatchlings) in groups, they are more often than not feeding on plants together.

First of all, I discovered your site many years ago and I love it!
Secondly, my sister sent me this photo and I referred her to whatsthatbug.com and she told me to do it because there were too many bugs on your site. LOL
I checked out the bugfinder site and though it listed 43 bugs, none of them seemed even remotely close to these bugs. All I can tell you is she was in her backyard and discovered this on her one of her plants and took a photo. They are orange /red and black insects with spots and there is even a larger bug that is a brownish color, underneath these colorful bugs. It is currently Springtime and the photo was taken on Wesnesday, May 18, 2016 at around noon, in Anahuac, Texas.
What exactly are these bugs and are they harmful to pets or people?
Thanks so much!
Thanks so much for the compliment, and we agree that upon a first visit to our site, the currently 22,101 postings can appear quite daunting, but knowing a category helps immensely with identification. These are True Bugs in the suborder Heteroptera, and they are Leaf Footed Bugs in the family Coreidae. They are all immature specimens. Adults are winged. We believe your species is in the genus Leptoglossus, and your individuals resemble the individual in this BugGuide image, also from Texas, that is identified as Leptoglossus phyllopus.

Orgy in the Cow-Peas
My boyfriend and I discovered scads of these bugs (after searching your website I think I’ve identified them as some kind of leaf-footed bug) all over our cow-peas a few weeks ago. They stayed there for at least several days, seemingly engaged in a giant orgy. They appear to have made dark spots all over our cow-pea pods. Is it possible that they layed eggs in the pods or the peas themselves? Best,
San Diego CA
These are mating Leaf Footed Bugs in the genus Leptoglossus, but they don’t seem to exactly match the species depicted on BugGuide. We suspect the black marks on the cow-pea pods are the result of the insects feeding. They have piercing and sucking mouthparts, and inject enzymes into the seeds and fruits of the plants they feed upon.

These are Big Legged Bugs or Leaf Footed Bugs in the family Coreidae, in the order of True Bugs, Hemiptera. Stink Bugs belong to the same order, but are in the family Pentatomidae. This species is Leptoglossus phyllopus, and it is considered a pest on ornamental and fruit crops where it sucks juices from plants and causes damage.

Please tell me he’s not a killer
After moving to Southern Colorado a few months ago, we have become huge fans of your website while attempting to identify many of the unknown insects (at least to us!) we have encountered here. We were prepared for the rattlesnakes, but it was the 4-5" Multi-colored centipedes, huge wolf spiders and a myriad of Black Widow spiders which caught us off-guard. Anyway, it all got to be a little too much for our 7-year old daughter when I was explaining to her that she needed to stay back from any shiny black spider she might find while out playing in our back yard and she wailed,"Why does everything here want to kill us??!!" (And up until this point I had thought I was doing a good job being calm and factual about the whole thing.) Anyway, we have been able to calm most of her fears regarding new bugs thanks to your great site. Here is one that has stumped us though. We spotted this little guy on the side of our stucco house a few days ago. He was between .25" and .5" long. His unique body shape intrigued me and I can only guess that it’s the larval stage of some common insect. My best guess was some sort of Antlion because we have something like those living in the dirt below where we found him. I would love to know what he is and also for my daughter– does he want to kill us??!! Thanks so much.
We quickly located Nisoscolopocerus apiculatus on BugGuide. Nisoscolopocerus apiculatus is an atypical member of the family Coreidae, the Leaf Footed Bugs or Big Legged Bugs. Other than the identification and the following description: “body mottled gray, pear-shaped (abdomen expanded, head and thorax narrow); wings short in adult, barely covering anterior portion of abdomen; antennae apparently 3-segmented, bent laterally almost 90 degrees after first segment; terminal segment spindle-shaped”, there was not much helpful information on BugGuide, except to say that it lives “on the ground in dry fields and savannahs.” Coreid Bugs are plant feeders and they will not harm you. Thank you for contributing a new species to our site.
Thanks so much for the speedy ID–it made a great surprise birthday present for me ; ) I noticed that the Coreid photos on BugGuide were from the county just north of us, so maybe it’s unique to this area. Regardless, I’m glad to know its relatively friendly. My daughter was also thrilled to see it posted on your site. As an artist-type myself who dreams up great projects which then take on a life of their own, I just have to say,”Keep up the great work. It’s appreciated!!”

Bug of the Month – Feb 2009, eating habits?
Tue, Feb 24, 2009 at 4:34 PM
Hi, I live in Phoenix, AZ and my kids and I were in our backyard and noticed these bugs my son refered to as “lobster bugs”. We came inside and found your site. Thanks for the science lesson! I was wondering if these plant bugs opened the pomagranate or did they find them and begin to eat them? Is this their plant of choice or will any do?
The insects in your photos are mating Leaf Footed Bugs or Big Legged Bugs, probably Leptoglossus zonatus as depicted on BugGuide. We often see this species on ripe pomegranates in Elyria Canyon Park in the Mount Washington area of Los Angeles. The adult insects are also attracted to our tomatoes. These insects have sucking mouth parts rather than chewing mouth parts. The Leaf Footed Bugs use their sucking mouth parts to pierce the skin and suck the juices from the plants. Enzymes that the insects release create bruise-like irregularities in the fruit. The ripe pomegranates split their skins on their own.
Letter 36 – Leaf Footed Bug, possibly Giant Agave Bug
I don’t think this is a leaf footed bug
Fri, Apr 24, 2009 at 7:34 AM
I took this picture today (4/24/09) in my wife’s herb garden. I tried to research it online and the closest I can come up with is a leaf footed bug, but I don’t think it’s a perfect match. We are located in Corpus Christi, Texas, and it is starting to get warm outside with relatively high humidity. If you are able to identify this bug, is it harmful to the plants? We only have herbs and flowers, no fruits or vegetables.
Corpus Christi, Texas
You are correct. This is a Leaf Footed Bug or Big Legged Bug in the family Coreidae. This is a family with much diversity. According to BugGuide, there are 33 genera and at least 88 species in North America. We believe your specimen is in the genus Acanthocephala. BugGuide lists five species and four are reported from Texas, though the information page on the genus on BugGuide indicates that all five may be found in Texas. We are not certain which of the species your specimen is, but the only one with a common name is Acanthocephala thomasi, the Giant Agave Bug which “Feeds on juice of the Agave plant, according to this site . Also feeds on legumes “. We doubt any of the species would ever be so plentiful as to damage individual plants.
Update: Wed, 6 May 2009 17:40:24 -0700 (PDT)
The leaf-footed bug from Corpus Christi, TX is indeed in the genus Acanthocephala, but it is unmistakably Acanthocephala declivis. That steep front edge to the thorax is pretty diagnostic.

What is this bug found lounging on tomato
September 30, 2009
What is this bug? Beneficial or harmful? The “mother” is present on two of the attached photos.
We are thrilled that your photo illustrates a multi-generational grouping of Leaf Footed Bugs in the genus Leptoglossus. There are no adults in your photos. Rather, these represent at least three different instars, the term used for a metamorphosis stage. After each molt, the nymph grows and changes. It is not until the reproductive adult stage is reached that the insect will grow wings that are fully functional. We believe they are probably Leptoglossus zonatus which may be viewed on BugGuide. We often find this species on our own tomatoes in our Mount Washington, Los Angeles garden, and on pomegranates growing in Elyria Canyon Park. Here is the information posted to BugGuide on this sucking insect: “Identification Two yellowish spots on the forward part of the pronotum are distinctive. Also has a zigzagging white band across the wings (like some other species). Expansions of the hind tibiae are also much larger and more jagged than most other species. Range Primarily a southwestern species (including CA, AZ, TX) but now also spreading into southeastern states. First LA report 1990s. First FL report 2005. Food Feeds on flowers and fruits of many plants, including many crops such as citrus, tomatoes, and various members of the squash family. Remarks Considered a pest not only for the feeding damage on various crops but also as a transmitter of plant pathogens.“
Yes, that’s them! Thank you for the quick reply and identification. I’m the only one I know that actually thinks they’re adorable. I’m always fascinated by the critters that decide that my backyard is a hospitable place to take residence. While they are considered pests, they have become members of the family the past week, so I’ll let them stay. Unless you advise otherwise.
Question, if there are no adults, is that NOT the mother that’s been brooding over the kids? OR is it possible that immature leaf-footed bugs can reproduce?
Earlier today, we posted an adult of the species found in Long Beach. The immature nymphs cannot reproduce. The behavior that you have labeled brooding is simply an aggregating tendency found in many True Bugs. Since tomato plants only last one season, any pathogens spread to the plant would not affect next year’s crop of tomatoes. We often let Tomato Hornworms and Katydids feed off of our plants. We also do not disturb the Leaf Footed Bugs as they are never plentiful. We do mercilessly remove aphids, and the new African Painted Stink Bugs from our plants, and we try to keep our citrus clear of Citrus Leaf Miners.
Letter 38 – Leaf Footed Bugs in Honduras
assasin or bad guy?
January 25, 2010
Hello, This bug was congregated with about 16 of his friends on the leaves of a tomato plant. I also found 2 of his cousins on an almost ripe tomato. They are slow moving and make no effort to fly. They have 2 red/orange dots on their sholders.
Balfate, Honduras (North Coast)
Hi Again Brad,
We already provided you with a very short answer, but now that time allows, and we are preparing to post your letter and images, we can give a more detailed answer. These are Leaf Footed Bugs in the family Coreidae, and they are immature nymphs without fully developed wings. Some tropical species in the family have greatly exaggerated hind tibiae, and they are known as Flag Footed Bugs. Perhaps one of our readers will be able to provide a more specific identification with regards to genus or species. Bugs in the family Coreidae suck nutrients from plants, but they are not generally a problem unless they are very numerous. An exception would be those that feed upon fruits including tomatoes. In California, we have a species of Leptoglossus that injects saliva into fruits such as pomegranate, and this renders portions of the fruit unpalatable. The same may hold for your species if it feeds upon the fruit of the tomato. We also believe that sixteen individuals feeding upon a single tomato plant may compromise the health of the plant.
Thanks a million for the great information. I have continued to inspect my garden for the presence of additional Flag/Leaf footed bugs, but I have not found any others. I find it interesting that they were all congregated on the one tomato bush and nowhere else. Thanks to your help I was able to learn a great deal more about this family of bugs and also gain some additional understanding on an unrelated pest (squash Vine Borer) in my garden. We are using our garden as a test plot for school garden projects we will be working with here in Honduras. Our learning curve is steep and we are grateful to have a resource such as yours.
Brad and Trish Ward
Hospital Loma de Luz, Balfate, Colon, Honduras
We applaud your noble efforts in Honduras. We suspect the reason that all the immature Leaf Footed Bugs were congregated on one plant is that they came from the same brood. Since they have not yet developed wings, they cannot fly to other plants. The winged female was able to fly to a choice food plant and lay her eggs, and since the plant was selected by the female as a food source, there was no need for the young to disperse.
Update from Karl
The two yellow/orange spots on the pronotum are characteristic of both the adult and late instar nymphs of Leptoglossus zonatus. The Bugguide also has an image of a nymph. The species ranges from northern South America to the southwest USA. According to Wikipedia: “In Honduras, where the bug is known commonly as chinche patona (large-legged bug), it is a minor garden pest.” It appears it may be extending its range eastward in the southern USA, and the Florida Department of Agriculture & Consumer Services (Division of Plant Industry) has recently issued a ‘Pest Alert’ for this species in Florida. Regards.

Mating Leaffooted Bugs on Thistle
April 13, 2010
I love your site and it has really helped me learn more about identifying bugs. I spotted this pair of Leptoglossus phyllopus (leaffooted bugs) on a dense thistle plant in central Florida just this past week. All the ‘webbing’ in the photo is just fibers from the thistle plant, which according to your site is the favorite haunt for this particular bug.
Your mating Leaf Footed Bugs are a marvelous addition to our website and our Bug Love pages. According to BugGuide, Leptoglossus phyllopus may be identified because: “The straight white or pale yellow bar crossing the back is distinctive to this species. In other Leptoglossus species it may be zig-zagging or broken into dots. In one species (L.ashmeadi) it is yellow-orange.” BugGuide also mentions its fondness for thistle.

This was in my garden in Austin TX. I was not sure if I should have chased it away or not. Since it scared me, I took its picture and left it alone 🙂 I don’t even know what category to look in?
This is an immature Leaf Footed Bug or Big Legged Bug in the family Coreidae, but we are uncertain of the species. The immature nymphs often look nothing like the adults which are more commonly pictured in identification guides. Additionally, the coloration of a freshly molted individual will quickly darken. Your photo of a molting immature Coreid Bug is quite stunning.

Orange Antenna’d Mating Stink Bugs?

The body of these bugs looks just like that of a Stink Bug, but these are black and have orange antennae. Also… they seem to be mating. Could you tell me what they are? This picture was taken today, north of Philadelphia, PA
These are actually Leaf Footed Bugs in the family Coreidae, not Stink Bugs. We believe they are Acanthocephala terminalis, which according to BugGuide can be identified by the: “Apical segment of antenna orange or yellowish, contrasting sharply with the basal three segments, which are dark; flange on hind tibia wavy-margined, narrowing distally and extending only two-thirds the length of the tibia; pronotum with small but distinct tubercles present, surface with covering of golden hairs; abdomen sinuate in outline, the sides of the abdomen bulging outward beyond the wings when viewed from above (these last three characteristics distinguish A. terminalis from A. confraterna).”

I found some Leaf-Footed Bugs mating on my tomato plants today, and I took a few pictures. In these photos I don’t see the yellowish spots on the forward part of the pronotum that were obvious in the first bug picture I sent you. So do I have two varieties of Leaf-Footed Bugs on my tomatoes?
Hi Again Karen,
These mating Leaf Footed Bugs are in the same genus as your previous submission, Leptoglossus, however they represent a different species. We believe this is Leptoglossus phyllopus based on images posted to BugGuide.
Thank you again for your help. At first I assumed these bugs were the same as the bug in the first photo I sent you, but when I looked at the pictures closely I didn’t see the spots on the pronotum. It’s hard to believe that I could have two species of a bug I’d never heard of or seen before on my tomato plants!

Dear Ranger Dan,
According to BugGuide, Leaf-Footed Bugs is the accepted common name, but we have also seen the common names Big Legged Bug and Flag Footed Bug applied to the family Coreidae. To avoid any confusion, you can stick to the family name Coreid Bugs. We wish you had supplied a dorsal view of the individuals you found. We suspect these are members of the genus Narnia based on BugGuide, and there are a few species reported from Arizona.
Thanks Daniel, After looking around a bit, I did come up with Narnia, also. Funny, I never even thought to take a shot from a different view. Now I know better!!
I put the picture of the Narnia on my blog as well as another leaf-footed bug, Chelinidea vittiger. Next time I come across that prickly pear, I will see if I can spot the Narnias again and get some better shots.
Hi Again Ranger Dan,
Based on this photo on BugGuide, we are inclined to agree that this is most likely Narnia femorata.

Any idea what these flying fast-breeding black insects are? We are in the valley in CA. Many thanks. Allan
California has many valleys. Are you in the San Fernando Valley? These are Leaf Footed Bugs, Leptoglossus zonatus. According to BugGuide: “Feeds on flowers and fruits of many plants, including citrus, tomatoes, various members of the squash family, and many other plants.” Close to downtown Los Angeles, we often find them feeding on the fruit of pomegranate trees.
Thanks so much for your response.
We are in Reseda, CA 91335.
The red container is a hummingbird feeder, and there are tomato plants nearby.
Perhaps they are attracted to the sugary liquid in the h.b. feeder, although they don’t seem to be on the feeder itself, just close by. Maybe they steal the juice at night time.
This is the first year (in the 4 years we have lived here) that I’ve seen them.
I’m wondering if they are harmful to humans at all?
Again, great service and thank you.
When we posted your photo, we cropped out most of the hummingbird feeder, and in our opinion, it is not relevant, however, we may be wrong. Leaf Footed Bugs, like other Hemipterans, have mouths designed for piercing and sucking, in this case, sucking the fluids from plants. Though they are not directly harmful to humans, they may spread viruses or other pathogens to plants, which BugGuide mentions: “Considered a pest not only for the feeding damage on various crops but also as a transmitter of plant pathogens.”

Since your question came to Daniel’s personal email address and not through the official WTB? website, you did not have to fill out a form which contains a location. We suspect since you live in Los Angeles and since there are ripe oranges in the photo, your friend took this photo in Los Angeles, though we have become such a global community through the internet so we do not want to make assumptions. Please provide us with a location. These are mating Leaf Footed Bugs, and since there are two yellowish spots visible on the pronotum, we are confident this is Leptoglossus zonatus, a common Southern California species. See BugGuide for additional information.
It was taken in Simi Valley.

These are newly hatched True Bugs in the suborder Heteroptera, and hatchlings may be difficult to identify to the species level. With that said, we believe these are newly hatched Leaf Footed Bugs in the family Coreidae, and there is a photo on BugGuide of hatchlings identified as being in the genus Leptoglossus that looks very much like your image. There are several members from the genus in Florida.

Hi again Dana,
Now that you have sufficiently fluffed our ego, we decided to dig through the trash, prepare your photo for the web, and provide a bit more information for a true posting. We believe this is a Western Leaf Footed Bug, Leptoglossus clypealis, based on the BugGuide description “A spine extending forwards from the tip of the head (the tylus) is distinctive.” See this image on BugGuide for a closeup of the tylus. A more dorsal view of this Leaf Footed Bug from above would make our suspicion more definite as the tylus is partially obscured by the antennae. Though we have already indicated this Western Leaf Footed Bug is not harmful to humans, BugGuide notes: “Can be a pest in pistacio, almond, plums” and we have also observed them feeding on pomegranates. They feed by piercing the skin of the fruit with their proboscis and sucking fluids from the plant. The release of an enzyme at the site of the feeding results in blemishes on the fruit that make parts of it inedible to humans.

Hey ! Me and my friends found a bug in our backyard, I can’t identify it so can you help us ? If you find out what it is,can I keep it as a pet ?
You can tell by the enlarged tibiae on the hind legs that this is a Leaf Footed Bug in the family Coreidae. They are not harmful, but you will need to provide it with the appropriate food if you are going to keep it. Leaf Footed Bugs feed on the fluids from plants, deriving nutrition by sucking the fluids with the piercing and sucking mouthparts. We believe your Leaf Footed Bug is a Citron Bug, Leptoglossus gonagra, which we identified on the Flying Kiwi site. We also found an image on this blog. According to BugGuide, it is “polyphagous” and a “minor pest of citron groves in FL, major pest on several crops in S. America.” If you have access to Citron, you can place a ripe fruit in the container to see it it will feed. If no citron is available, try an orange.

This bug is eating my monarchs. What kind is it and what can I do to prevent them attaching my monarchs.
How you want your letter signed: Kathryn e
We need some clarification. How do you know these Western Leaf Footed Bugs, Leptoglossus clypealis, are feeding upon your Monarchs? Are they feeding on adult Monarchs or Monarch Caterpillars? Leaf Footed Bugs are not known to be a predatory family. Furthermore, they would not be feeding upon milkweed which is the only place they would encounter Monarch Caterpillars. We seriously doubt your claim which is why we would like to know details. The Western Leaf Footed Bug can be distinguished from other similar looking members of the genus by the presence of a spine on the head known as a tylus, a feature pictured on BugGuide.
First let me thank you for taking the time to help me. I know you and others volunteer your time for which, I am very grateful. I am new to studying Monarchs as I have started planting milkweed, caring for eggs, larva, and butterflies, releasing Monarchs here in AZ, and documenting data with the SW Monarch Study for the last two years. This is my first foray into bug identification and study.
Thank you for letting me know the name of the bug and I am glad to know he is not a predator. I have an abundance of aphids, Assassin bugs, and green lacewings so there is much going on in the garden.
Thank you so much for volunteering your time, it is truly a gift.
Thanks for responding Kathryn,
If we are understanding your response correctly, you merely suspected this might be a Monarch predator and you have no actual first hand observations of any predation.
Yes, that is correct.
