Oleander Caterpillar and Milkweed Assassin Bug

Hi Walt,
The caterpillar in your photo is known as the Oleander Caterpillar, and it is the larva of the Polka Dot Wasp Moth, Syntomeida epilais.  Below the caterpillar is an immature Milkweed Assassin Bug, a predator that often feeds on caterpillars.  We  are uncertain if it will prey upon the Oleander Caterpillar.  The caterpillar stores toxins from the oleander in its body which renders it unpalatable to many predators.

Wheel Bug

Insect With Gold Wing Tips
October 4, 2009
I was hiking around Sugarloaf Mountain with some friends when we spotted this odd insect. I looked around trying to identify it, but couldn’t find anything so I thought I’d ask.

Hi Brian,
This is a Wheel Bug.  Not all Wheel Bugs exhibit this coloration, and it may just be the way the light is reflecting on the wing membranes.

Leaf Footed Bug

Unknown bug species
October 3, 2009
My mother in law found this bug on her Pomegranite tree in her front yard on 10/2/09. She has lived at that house for 40 years and has never seen this bug before.

Hi Linda,
This is an adult Leaf Footed Bug, Leptoglossus zonatus.  We just posted an image of immature nymphs feeding on tomatoes.

Immature Leaf Footed Bugs

Hi Lori,
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.

Hi Daniel,
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?
Regards,
Lori

Hi Lori,
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.

Immature Florida Predatory Stink Bugs

Beetles (?) on grapevine
October 2, 2009
I noticed these colorful guys piled up on the leaf of our wild grape vine this morning (Oct. 2), and would be interested to know what they are and what they might be doing (there’s not a lot of obvious activity). As you can see, they are cherry red on the back with twin black markings. The head and segment closest to the head are glossy black, with black antennae. They are roughly half an inch end-to-end. I don’t recall seeing insects with these markings in the area (Accomack County, Eastern Shore of Virginia) before, and certainly not in a cluster like this. Thanks for your help.

Florida Predatory Stink Bug Nymphs

Hi Linda,
Despite you writing from Virginia, your bugs are Florida Predatory Stink Bugs, Euthrhynchus floridanus.  BugGuide indicates:  “Predatory on other insects, including caterpillars, beetle. Nymphs, and to some extent, adults, are gregarious, and may attack large prey in groups.
“  The orange and black adults are sometimes called Halloween Bugs since they appear near the end of October.

Bed Bug

Do I have bedbugs??
September 27, 2009
For about the past two weeks, I’ve been getting at least one bite per night. I don’t know what it is! Help!
The bites started mostly on my lower body with a few on my hands. The first few nights I woke up with severe itching and several bites – more than a dozen each night! The bites went from the soles of my feet and in between my toes to the backs of my calves and seemed to culminate in a giant cluster on my hip that swelled up to about the size of an Oreo cookie – it looked like a group of 6 or so bites. A couple mornings later I woke with a handful scattered just below my collar bone. I’ve had a few on my arms and one on my stomach, but I’ve lucked out and haven’t gotten any on my face (knock on wood).
At first the itching lasted a few days but for the last 3-4 days, the itching has been isolated to one day, is not as severe, and I have only been getting a single bite per night. As the bites have healed, they have left an area of hyperpigmentation… I can still see where the bites I got in the beginning were – they almost look like little bruises now, but they’re not tender.
I only got bit when I slept in my bed – I slept on the couch one night (I just couldn’t stand the bites anymore!) and was bite free! My husband has not gotten ANY bites, though!! Could whatever’s biting me prefer my blood to his? Are they maybe just on my side of the bed?
We have set off a bug bomb and changed the sheets. I also gave my cat a flea treatment just in case. Interestingly, I have been finding scabs around her collar (maybe a coincidence?) – this started a few days before I started getting the bites, but I have not seen the cat scratching herself. We also put out some adhesive rodent/insect traps, but have not caught anything on them.
Today I found a strange little bug that I’d never seen before. I found it on my knee… crawling about on my jeans in the middle of the day. I saved it in a cup and my husband took a photo when he got home. You can see our little bug in the photo next to a dime and the head of a pin. It’s super tiny and mostly round, about the size of a sesame seed. No wings. Six legs. Brownish, kind of opaque. Do you think this critter is the culprit? Can you tell me what he is? I was thinking maybe a baby bedbug… but obviously I’m no expert! I kind of hope that’s not what he is because where there’s babies, there’s got to be grown-ups!
I am sick of these bites and want the bugs GONE! Thanks so much!

Hi Tarra,
We agree that this is an immature Bed Bug.  You can see a photo on BugGuide that matches.  During the day, Bed Bugs hide from the light, and they can be found between the mattress and box spring, between the base board and the wall, and behind pictures hung on the wall.  Good luck with the eradication.

Daniel:
The couple with the bed bugs needs to seek a professional extermination service, or have the landlord do so if they are renting.  Bed bugs are one of the few household pests that really requires the professionals.  The eradication process is very invasive, though, as you literally have to take apart the bedroom and furniture to get to the bugs.  Be prepared for at least three visits from the exterminator, and probably more to guarantee the success of the effort.
As for Tarra’s husband not getting bitten:  he is, he just isn’t reacting to the bites.  Every person’s immune response is different, and clearly Tarra is more sensitive than her hubby.  She should make sure her symptoms don’t worsen, and see a physician if they do.
Lastly, bed bugs often ignite legal warfare as well, as landlords seek to hold tenants responsible, even if they are not the ones who introduced the bed bugs.  So, I always recommend seeking legal advice when approaching this kind of problem.  Yes, good luck with the eradication!

BUG OF THE MONTH OCTOBER 2009: Large Milkweed Bugs

Unidentified Milkweed Bug?
September 26, 2009
I came across these bugs while working on one of our nature preserves. I have seen the bug before but not in this context. There were several of these inside of the seed head of a couple milkweed plants. What is this bug and what is its ecological relationship with milkweed?

Large Milkweed Bugs

Large Milkweed Bugs

Hi Derek,
This is a group of Large Milkweed Bugs, Oncopeltus fasciatus.  The winged individuals are the adults and the others are immature nymphs.  The food plants are plants in the Milkweed and Dogbane families.  The insects feed on the juices of the seeds of the plants and will not harm the plants, and adults also take nectar.  According to BugGuide:  “In the course of feeding these bugs accumulate toxins from the milkweed, which can potentially sicken any predators foolish enough to ignore the bright colors which warn of their toxicity.”  We found a nice Milkweed Bug Information page posted by the University of Arizona that has useful information.  This is the third letter with an identification request for the Large Milkweed Bug that we have opened today.  Your photo is quite beautiful and we are selecting your letter and photo as the Bug of the Month for October 2009.  Throughout the month of October, it will remain at the top of our homepage.

Hi Daniel,
I would be honored to have my photo posted for the October bug of the month. Thank you for this information and your quick response. I am very impressed with the web site. I do nature preserve management for The Nature Conservancy and often come across interesting insect specimens. I will surely be in touch.

Hi Cathy,
These are immature nymphs of the Large Milkweed Bug, which we just identified for you.  Like other Hemipterans, they have sucking mouthparts, and they feed on juices from the seeds and seed pods of milkweed and dogbane.  We have never located any information that this is a problematic species in the garden.

Scentless Plant Bug

Two mystery bugs
September 21, 2009
Bug #1 – Brown, six legged with wings and looks to be a stinger. About 2 inches long. Found dead on our driveway.
Bug #2 – Brown and white spotted bugs with orange spots almost like a lady bug. Found on our althea red heart hibiscus buds.

Scentless Plant Bug

Scentless Plant Bug

Hi again Heather,
Bug #2 is a Scentless Plant Bug, Niesthrea louisianica, and it has no common name.  According to BugGuide, it:  “Feeds on flower buds and seeds of plants in the Mallow family (Malvaceae), such as Hibiscus and Rose of Sharon.
“  More importantly, BugGuide also indicates it is:  “Used as a control of the invasive annual weed, Velvetleaf (Abutilon theophrasti). In one 1987 study mentioned here it was found to reduce seed production by 98%.“  The brightly colored immature nymphs in your photo are wingless, but your photo also shows a winged adult, though the individual is not the point of focus in your photograph.

While out scouting for butterflies, I came upon this slightly grizzly scene of a wonderful assassin bug dining on a Japanese beetle. Glad it wasn’t me!

Hi Lynne,
Thanks for sending your wonderful Food Chain documentation.  More specifically, the Assassin Bug is a Wheel Bug.  We are sure your photo will bring great joy to many gardeners who are plagued each year by the appearance of the scourge, the Japanese Beetle.  The invasive exotic Japanese Beetle appears in great numbers each year and feeds on many ornamental and food plants, including roses.  We have heard that this year in Ohio, the Japanese Beetles can still be found despite the late date.

Milkweed Assassin Bug

Milkweed Assassin Bug

Hi Carrie,
Your insect is a beneficial predator known as a Milkweed Assassin Bug that will help keep your plants pest free, though they will also prey upon beneficial pollinating insects.  Treat the Milkweed Assassin Bug with respect as they might give a painful bite if carelessly handled.
