Giant Mesquite Bug Nymphs from Mexico

A Strange and colourful beetle – What is it??
March 21, 2010
I found this cluster of beetles in Cancun Mexico this past week. I found them in the late morning, and I would have been scared by their size (about as long as my thumb) if they weren’t so beautiful! I’d love to know what they are and any extra information about them!

Giant Mesquite Bug Nymphs

Hi Bekki,
This is not a beetle, but rather a true bug in a different order.  These are immature Giant Mesquite Bug in the genus Thasus, but we are not certain if it is a different species, or a subspecies, or merely a color variation of Thasus neocalifornicus, a species found in Arizona and California that is represented on BugGuide.  We suspect it is either Thasus acutangulus or Thasus gigas, both of which are found in Mexico.  A Threatened Edible Insects in Hidalgo Mexico website indicates the following about Thasus gigas:  “Xamues (Thasus gigas Burm.) (Hemiptera-Coreidae)  Thasus gigas live in the “mezquite” tree (Prosopis juliflora (S) DC), their only host, and are also known as the “mezquite worm”. The species was very abundant in this area, but now that a larger number of adults and larvae are gathered for sale rather than for personal consumption, the abundance of this species has declined. This species is univoltine, and it is collected in the spring [14]. Elderly people in the study area who eat this species, say that they can currently only find few specimens at a time, allowing a one to two month supply, while in the past they could gather enough to feed on for six months. They refer to this species as the “meat we eat”. This insect is greatly appreciated because of its sweet taste, which is rare in the rural areas. After they are gathered, the insects are dried on a griddle, stored in plastic mesh bags, and hung in the kitchen where they provide a daily meal.
“  Additional searching leads us to believe that this may be Thasus acutangulus, based on the photo of an immature specimen on the Alex Wild Photography website.  There is also a photo on Flickr.

Immature Coreid Bug? or Immature Assassin Bug???

Black insect with raised, red sides; four ridges on top of abdomen
March 19, 2010
Last spring I found this insect while out exploring and I am curious as to what it is. I tried my insect field guide but could not identify it. It was found on a rock midmorning in April in Riley County, Kansas.

Assassin Bug? or Coreid Bug???

Hi Danielle,
This is an immature True Bug, and guide books rarely depict immature specimens in photographs.  We wish your photograph showed the face of the bug.  At first we thought this was an Assassin Bug, possibly an immature Bee Assassin in the genus Apiomeris as depicted on BugGuide, but its legs are rather hefty, so we would not discount that it might be a Big Legged Bug in the family Coreidae.

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.

Immature Leaf Footed Bugs

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.

Immature Leaf Footed Bug

Daniel,
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.
Cheers

Hi Brad,
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
Hi Daniel:
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.
Karl

Clown Bug

Dear Jeff,
Generally, we only like to post one species of insect, or at least only closely related species in the same posting, and we prefer that letters be more than a list, as information that is provided is often very helpful for identification purposes.  Detailed letters are also much more entertaining than reading a list.  With that said, your first and third images are both in the same family, Coreidae, commonly called the Leaf Footed Bugs or Big Legged Bugs.  In the case of your specimens, Big Legged Bugs seems more appropriate.  We suspect that your two images might be the same species, as nymphs are often more brightly colored than adults which are winged.  We researched this on the Brisbane Insect website and we believe you have submitted photos of a Clown Bug in the adult and late instar nymph forms.  The Clown Bug, Amorbus robustus, is also called the Eucalyptus Tip Bug.  Your photos are beautiful.

Leaf Footed Bug: Acanthocephala declivis, a Pumpkin Bug

Pumpkin Bug?
January 19, 2010
My kids spotted this big guy crossing our road yesterday. My mother said my grandmother used to call these pumpkin bugs. Since my grandmother also thought a shot of whiskey cured anything that ails you, I’m not sure I trust her bug identification. We did notice it had two sets of wings and six legs, leading my son to think perhaps it was a beetle. He was about 1.25″ long from head to abdomen. Can you help us identify it? Also can you offer information about handling insects and which ones might bite? We tend to use sticks and leaves to move insects since I’m unsure what might bite when I can’t identify it. Thanks so much for your help!

Acanthocephala declivis: The Pumpkin Bug

Hi Resa,
We are on a mission to prove your whiskey swilling grandmother correct.  This is a Leaf Footed Bug, a name applied to the entire family Coreidae.  Leaf Footed Bugs are also called Big Legged Bugs or Flag Footed Bugs, though the latter name is generally reserved for some tropical species with even more greatly developed tibiae on the hind legs.  The family, according to BugGuide, is also referred to as the Squash Bugs because many of the 88 known North American species are plant pests that feed on members of the squash and melon family.  A pumpkin is a squash, so maybe Pumpkin Bug was a local name for your species, Acanthocephala declivis, which does not have a specific common name according to BugGuideBugGuide cites a University of Florida website with this species identification:  “Humeral angles of pronotum broadly expanded, extending laterally well beyond maximum lateral abdominal margin. Distal dilation of hind tibia broad until apex, then curving in at right angles to tibial shaft. Anterior pronotal lobe with 2 small shining blunt tubercles along midline.
“  Try as we might, we are unable to locate a website that specifically connects Acanthocephala declivis to pumpkins, but we trust the wisdom of the ages, and we truly believe your grandmother must have known something.  Perhaps she grew pumpkins and found Acanthocephala declivis feeding on the plants each year.  Pumpkin Bug is surely much easier to pronounce around the dinner table than Acanthocephala declivis is.  In honor of your grandmother, we are going to unofficially proclaim Acanthocephala declivis the Pumpkin Bug.  Ailing or not, we think you should drink a shot of whiskey to your sagely grandmother today.

Western Conifer Seed Bug

Fall and over winter visitor
January 16, 2010
I have an insect that is probably 1/2 in long not including the head. It has a rusty color (the wings?) and white lines on the sides under the wings. It seems to be found near my slider to the deck. It also finds its way upstairs. It can makes a low buzzing noise when it clumsily flies around like a helicopter. It’ss slow and easy to catch. I just started to see them with the cooler weather in November and now in January continue to see them. What should I do with them? I don’t like to harm bugs. It has six legs. Here’s one at my blog http://naturalworlds.blogspot.com.
Can we co-exist? Will it eat my house that is mostly wood? Thank you in advance. Your site is wonderful.

Western Conifer Seed Bug

Hi tess,
WE have posted several photos of the Western Conifer Seed Bug, Leptoglossus occidentalis, in the past week.  This harmless Leaf Footed Bug often seeks shelter indoors when the weather turns cooler.  It will not harm your home, its furnishings, nor its inhabitants.

Thank you very much. That is indeed my bug!  I won’t be in a hurry to throw them out the door into the cold since, according to what I’m reading, they will let themselves out in the spring.
Thanks again,
teresa

Western Conifer Seed Bug

Hi Susie,
We just finished posting another letter of a Western Conifer Seed Bug, Leptoglossus occidentalis, that had been smashed, so it is nice to follow that with your photo of a living specimen.  Western Conifer Seed Bugs are native to the Pacific Northwest, so this is a local native insect for you.  Adults often seek shelter indoors when the weather begins to cool.  They will hibernate and become active again when the weather warms in the spring.  They are a benign species that will not harm you, your home or its furnishings.  Adults and nymps feed on the sap from the cones of conifer trees, so they don’t even damage the host trees.

Daniel,
Thank you so much for the ID and the helpful information.

Western Conifer Seed Bug killed because of a distant relative

Crawling on the TV in my Daughters room
January 15, 2010
I had woken up at around 3:30am and checked in on my daughter. When I turned on the light I saw this little example of mother nature crawling his way to wherever he was going. So I did what all mothers do when they feel thier children are in danger, and whacked it with a shoe till it stoped moving. I took a close look at it and realized it has a close resemblence to a kissing bug. Which got me very scarred. I like in a well maintained apartment building in Peekskill, NY and it’s the middle of January. Could it really be one of those nasty little blood suckers, or do I owe it a apology and a mtachbox burial. I am very concered because it was so close to my daughters bed. Please if someone could get back to me I would greatly appreciate it.
Sincerest thanks

Western Conifer Seed Bug smashed with a shoe

Western Conifer Seed Bug smashed with a shoe

Hi Karla,
This is a Western Conifer Seed Bug, Leptoglossus occidentalis, one of the Leaf Footed Bugs that somewhat resemble another family, the Assassin Bugs, which includes the problematic Kissing Bugs or Bloodsucking Conenose Bugs in the genus Triatoma that may spread Chagas Disease.  You were astute to recognize the resemblance since they are in the same order of insects, Hemiptera, which includes all True Bugs.  The Western Conifer Seed Bug is a benign species that is native to the Pacific Northwest, but since the 1970s its range has increased greatly to include much of the Northeast and Canada, and very recently, portions of Northern Europe.  We are going to tag this entry as Unnecessary Carnage, and in order to prevent any retaliations, we are not including your surname in our posting in order to allow you to maintain anonymity.  We are doing this because we have received threats in the past from folks whose letters were tagged as Unnecessary Carnage that accused us of libel and warned us they would take legal action against us with frivolous lawsuits.  We do not blame you for your first reaction, and we understand your fear of a perceived threat.   We hope in the future you will recognize that Western Conifer Seed Bugs, which often seek shelter indoors as the weather cools, are benign, and then promptly relocate them rather than squashing them.  A matchbox burial would be sweet, but we think it is unnecessary.  We would happily restore your surname to the posting if you give us permission.

Unusual Hemipteran Phenomenon: Leaf Footed Bugs and Shield Bugs Swarm ship in Mauritania

Shield bugs
January 7, 2010
A while back I was working on a ship in Mauritania. These shield bugs arrived on board in a squall 30 miles off the coast. 80% of the vessels deck areas were covered in them. What are they, and what would cause them to be in a squall so far from land in such numbers??
Great site, Alan

Swarm of Hemipterans

Hi Alan,
What a bizarre occurrence.  We wish you provided a close up photograph of an individual insect.  First, the majority of the insects seem to be the same species, but there are some bright green individuals that look more like beetles, possibly Leaf Beetles in the family Chrysomelidae or Jewel Beetles in the family Buprestidae.

The swarm itself does not appear to be Shield Bugs, but they are True Bugs, possibly some plant feeding species in the superfamily Lygaeoidae.  We wonder if one of our readers can explain this unusual phenomenon.  We are guessing it was a population explosion that somehow got swept out to sea.

Hi, Daniel:
The brown bugs on the ship are something in the family Coreidae (leaf-footed bugs, squash bugs).  The green “beetle” is actually another true bug, a shield bug in the genus Callidea or Calliphara.  It is easier to tell from the distant image than the close-up!  The awkward angle of the close-up does make it appear to be a buprestid, I agree.
Wish I could be of more help.  The coreids should be easy for a European entomologist to identify, but I’ll keep looking, see if I can come up with something.

Giant Milkweed Bug

Is this an assasin bug?
December 28, 2009
Hi, I love your site. While visiting a relative in Naples, Florida, I photographed this bug near a beach. I think it’s an assasin bug, but I can’t find a matching image. It flew away when I got close. Any ideas?

Hi Sammy,
Though it resembles an Assassin Bug, this is actually a Leaf Footed Bug in the family Coreidae known as the Giant Milkweed Bug, Sephina gundlachi.  According to BugGuide, it is found in Florida, and has not been reported from other states.

Western Conifer Seed Bug

Stink Bug
December 20, 2009
This bug shows up at my parents house (the house is in a wooded area) every fall. They are pretty flat bugs and seem to crawl into the house under doors and windows. We find hundreds of them around. No one we’ve ever talked to can seem to identify them. Not even exterminators. We call them a “stink bug” because they give off a relativley fowl spell if you step on them.
I would be happy to give you more details if you need. Thank you!

Hi Rob,
The Western Conifer Seed Bug, Leptoglossus occidentalis, often enters homes when cold weather arrives so that it can pass the winter in hibernation.  It is a benign species that will not harm your home, your furnishings, your pets nor you.

Western Conifer Seed Bug in UK

a very menacing looking bug turned up in my front room apartment. my letter explains all.
December 5, 2009
hello sir’s
on saturday 5th december i was removing the throw-over from an armchair in my front room (which is carpeted, and i own a indoor cat, and live at the top of a three story apartment – i might add, if it helps) i moved the chair out of my way and noticed an odd bug which may have been hiding/residing under the chair? it wasn’t mobile moving (i accidently broke one of its legs moving the chair (i’m sorry). any way, it was still alive. having rescued it, i placed it on an envelope to inspect it. i’ve never seen one of these before so i took some snaps of it, however after searching for this unique scary looking specimen in my ‘bugs and insects’ book i’m still not aware of the species.
the closest ‘relation’ looking insects i could find that looked even remotely like the one i found were either a ‘house’ or ‘field cricket’, a ‘water boatman backswimmer’ or a ‘forest bug’? but, what i don’t know is if insects, say, like black ants are easily distinguishable from red ants because of color, size and the like, being the same genus etc…….
i still think this particular species is not any of what i read up on. although similar looking. this one is very distinctive compared to the researched ones i read about.
my girlfriend had been traveling around eastern europe for the summer and, may of unknowingly smuggled it back england in her traveling bags?
if you guys know what species it belongs to could you please enlighten me with your knowledge.
i’m not a worry-guts but the insect does look rather menacing, and as i’m ignorant to what family it belongs and where it came i’ll house it in a glass jar. in case you need further photography.
i hope it’s not poisonous or, being female, laid a nest in my flat.
last thing, my girlfriend returned back to england around mid june,
so if it did manage to find its way into our front room it would be
highly unlikely that it managed to survive five months or so.
please help.
yours faithfully

Western Conifer Seed Bug

Western Conifer Seed Bug

Dear Mr. Jake Bennett,
This is a Leaf Footed Bug in the family Coreidae.  We are nearly certain it is Leptoglossus occidentalis, the Western Conifer Seed Bug that is native to the Northwest region of North America.  Beginning in the 1970s, there were reports coming from eastern North America, and it is believe that an accidental introduction led to a range expansion.  In the 1990s reports of the species spread to the northern portions of Europe became more frequent.  There is a flickr page with reports from the UK.  Your girlfriend may have transported this specimen from the northern parts of Eastern Europe, or the species may already be naturalized in your area.  The Western Conifer Seed Bug often seeks shelter indoors as the weather cools, reemerging in the spring to lay eggs.  The species is considered harmless, though its increased range expansion may have as yet unknown effects on the species diversity within its adopted habitat.

Thank-you ever so much for replying to me on your website Sir, and the quickness of replying by e-mail too !!!
It’s very interesting and helpful. So thank you very much.
My questioning/story to you about my new best friend LFB was, totally something new for me.
Finding a devilishly looking critter (that I’ve never seen or know of in my life), in my own
lounge threw me a bit.
I would’ve spent hours, (more like days), hunting down genuine knowledge on the insect with-out your
rapid response.
I am really rather glad I came across him, being ignorant (totally) about insect genus’, I’ve found a new
interest, which is a great result.
I’ve moved him to a square plastic container as he couldn’t stick on the glass and resulted falling on his back
constantly and him being crippled at the moment I had to check him every half hour or so.
I’ve been trying to find – what I can feed him? to make him more comfitable whilst his back left leg mends
(if it ever will).
Saying that, he looks on the mend and is moving about -mostly on all other legs, while trying self physiotherapy!
One thing I have learnt though is, as much as they like fruit crops sugars etc.. never to
give them honey. He liked it so much that he covered himself with what he didn’t eat and kept falling on his
back and getting stuck.
Although | managed very gently to remove the honey from him I need to keep a close eye (just in case
I missed some).
Any who, he has lots of ivy plant shoots with him so if he gets stuck upside down again he can grab a bit
and pull himself back upright.
Mr Marlos, and my LFB have made my weekend.
I hope you have a good weekend also,
All the best.
Jason.
PS. I’ll let you know how he progresses if you’d like. Plus any tips from you would be great.
Q. Is there one particular fruit/food the Coreidae enjoy? preferably ‘non-sticky.
I’ve looked around the net
and all I found literally was multiple ways of exterminating them!!!!! which is for me a No-No.
