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?

Immature Broadheaded Bug

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.

Wow!! Thank you! That explains why I was unable to find it in any ant identification guides.

Broad Headed Bug Nymph

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.

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.

Broad Headed Bug

Dear Ken,
This is a Broad Headed Bug in the genus
Hyalymenus, possibly Hyalymenus longispinus which is pictured on BugGuide and which is endemic to Florida according to BugGuide.  Though there are no photos available of the other two species, BugGuide notes:  “3 spp. restricted to FL (H. longispinus, H. notatus, H. potens).”

Hello
I saw this insect working its way up a cedar tree outside the job. Thought it was an ant at first yet it appears to have some type of wing structure on its back. Not sure what it is. My guess would be a wingless wasp. It resembles a velvet ant minus the velvet. Feel free to post if you find this insect interesting.
Thanks

Broad Headed Bug

Dear Calvin,
This is an immature Broad Headed Bug which is believed to mimic the appearance of an Ant.  Ants are in the same insect order as Wasps, Hymenoptera.  Your confusion makes perfect sense.  Immature Broad Headed Bugs effectively mimic Ants.  Broad Headed Bugs are often called Ant Bugs.  Here is a photo from BugGuide of an immature Broad Headed Bug in the genus
Alydus.
