My family and I are living in Xalapa, Mexico for the year. We have many of these faux-bark creatures and I am fascinated! I have no idea what their classification is. I have tried desperately to find them on the Internet, but have so far found nothing. They are about 1/2 inch long. They have a little caterpillar-like head but their bodies (shell?) look like bark. I have also found them going up and down webs or silk from the ceiling. They stick to the ceiling, plants or anything with their exposed mouths. The one on my house plant is eating the leaves, but not too many, so I let him/her stay. Thanks for all you do!

Hi Tamara,
Certain Inchworms in the Geometrid Family exhibit similar camoulfage tendencies. That is our best gues

Thank you for your photo of a female Banded Argiope, Argiope trifasciata.

I know you’ll be so excited to receive yet ANOTHER email asking…do you know what kind of bug this is? I live in San Antonio, TX and have found these bugs in my garden just in the last couple of weeks. I can’t quite tell if they’re damaging my plants or not, but they are everywhere and multiplying rapidly. I really appreciate your help!

Hi Cara,
Your photo is rather blurry, but we are almost certain you have Harlequin Bug nymphs, Murgantia histrionica. This is a type of Stink Bug that often infests cabbage plants and wild mustard. They can get very plentiful.

Tiny Black Bug pics on a dime…
Great website, wonderfull resource! We just moved into a house this week I have no idea what these are, but I found about 10 of them around my window this morning lying around barely moving.
Hope you can help,

Hi Jesse,
This appears to be some species of Grain Weevil, a type of Pantry Beetle. They infest stored grain products. It is possible they were somehow left behind when the previous tenant vacated. Without a food source, they are trying to get outside and are dying.

what are these buggers?
Dear Dr Bugman,
We have suddenly and violently been infested by these tiny mites. My boyfriend is bitten (and itchy) all over but I have not been touched. We think they have come in through the window and are speculating that they could be from the nest of pigeons below our window. I have included a few photos. You can see them against the frame of my powerbook…that frame is about 1/3" wide. The smallest ones are white, the slightly larger ones are a dark brown. They appear to have 2 antennae. We just fumigated with a product from the store. What are they? Will this work?
thank you so much,
Laila Ames

Hi Laila,
The symptoms you describe are consistant with Bird Mites, but we can’t give you anything more conclusive based on your photo. From what we hear, biting mites can be very difficult to erradicate and may take professional help. Good luck.

on my eggplant
These bugs are freaking me out! They are crawling up my eggplant plants. As you can see, they look like double decker armored ants. They are with an ant in this photo and they seem to live peacefully with the ants except that I don’t know what’s happening with that ant which looks a little like it is in midair and I’m not sure why. The plants have ants on them too. I am scared of these bugs! Should I be? Will they eat the eggplants? I finally have a couple eggplants on the plants and I am looking forward to eating them myself and I don’t want to share with weird looking bugs.
Please advise.

Dear Lisa,
You have immature Keelbacked Treehoppers, Antianthe expansa, which often infest eggplants and other solanaceous plants like tomatoes and peppers. They will not eat your eggplants, but they will suck the juices from the plant stems. Treehoppers are related to aphids and also have a symbiotic relationship with ants. The Treehoppers secrete honeydew from their anuses and the ants love to lap up the sweet treat. The immature Keelbacked Treehoppers are quite spiny and can pinch. The adults are green and winged. When they feed on the plant juices with their sucking mouthparts, they sometimes spread viruses to the plants. They are injurious and should be eliminated from the garden either with soapy water, or our favorite method, squashing.
