Hello there,
I’ve found a few of these insects inside my house in the last three days. They only come out at night and seem to be attracted to light, since that’s where I find them most of the time. I have no ide show they got inside the house, because I don’t leave the door open and any search I did trying to find the point of entry hasn’t been successful. They look pretty intimidating to me! Could you help me ID this insect and if I should be concerned about my health?

Texas Bow Legged Bug

Your image nicely illustrates why this Broad Headed Bug, Hyalymenus tarsatus, is commonly called a Texas Bow Legged Bug.  According to BugGuide:  “on a variety of plants, especially euphorbias and seed pods of legumes and milkweeds” and in our opinion, it poses no direct threat to your health.

Thank you so much Daniel for your help and prompt response!
Now I can safely trap them and put them outside without losing my mind.
I can definitely see where their name comes from. They have a beautiful green color as well.
Thanks again and have a wonderful day,
Patricia

Dear Kimberly,
We believe we have correctly identified your Broad Headed Bug as a member of the genus
Hyalymenus thanks to images posted to BugGuide.  All members of the family are plant feeders according to BugGuide.  Because of your location, there is a good chance this is a Texas Bow-Legged Bug, Hyalymenus tarsatus, which is pictured on BugGuide.

Hi, I spotted this guy on my crape myrtle this morning. It has long legs, horns on its thorax, and a bumpy abdomen. What is it?

Dear Kristine,
Though it looks like an Ant, this is actually an immature True Bug in the family Alydidae, the Broad Headed Bugs.  It looks like this immature
Alydus nymph pictured on BugGuide.  There is also a nice image on Fotolog.

Dear Shane,
This is an immature Broad Headed Bug in the family Alydidae.  According to BugGuide, Broad Headed Bugs are : “All phytophagous; Alydinae feed primarily on Fabaceae (often on seeds); Micreletrynae, mainly on grasses.”  Though we cannot provide you with a species name, we did find a visual match to this “not yet identified nymph” on BugGuide.

Hello,
I live in South Texas (rio grande valley), and have noticed a colony of ants I have never seen before. They showed up in our garden (lots of mulch, cucumbers, sweet potato’s, papaya plants, banana plants, etc.), and have very distinct characteristics. They move very quick, I could swear I saw one jump, and their abdomens do an odd bouncing up and down when they approach another ant from their colony. It almost looks like they chase one another sometimes. Their antenna have a white tip, but they are otherwise black.

Broad Headed Bug Nymph

Dear Brandon,
While this is not an Ant, it is a very convincing ant mimic.  We believe it is an immature Broad Headed Bug in the family Alydidae.  According to BugGuide:  “nymphs are often ant mimics” and they feed “primarily on Fabaceae (often on seeds).”  Do you have beans or peas in your garden?  Your photo is not very sharp and it might also be an immature Damsel Bug which is a predatory species.

Daniel,
Thanks for the response! After looking at google search photos I believe you are correct. That explains the peculiar behavior. I’d point out that it does look like a whole colony of them. Also the only seeds in this area are our sunflower plants. No beans or peas. Ill try and get a better resolution photo for you soon if they are still there. Thanks for your help.
Brandon
