Who are these actors and what activity are they engaged in? Is one a male and one a female? Is one giving birth to the other? What is that gray worm-like thing coming out of the face of the larger? Why are the antennae of the winged smaller curving back to the thorax of the larger? Etc. Is this a unique photo? Can’t find anything like it on line!

Metamorphosis of a Stilt Bug

Dear Bill,
The activity depicted in your image is metamorphosis.  The green nymph is emerging from the exoskeleton of an earlier instar so that the insect can grow.  Because of the proboscis, this insect looks like it might be a Hemipteran, possibly an Assassin Bug, but we are not certain.  We have requested assistance from Eric Eaton in the identification and classification.  It is a lovely image.

Eric Eaton Provides Identification
Wow, what an amazing image!  That is a stilt bug, family Berytidae.

Many thanks! I can now put it up on Capture Arkansas.

I am having difficulty identifying a particular insect dwelling on my lagenaria gourds. The attached images show an adult and a pair of immature insects. They can fly, at least short distances, but they keep the wings against these body when at rest and the wings are inconspicuous at that time. They seem to be reproducing quickly. I would rather not remove a beneficial insect from my garden but I suspect they are sucking insects–they have a thin probe-type extension that they seem to be using to feed, much like a mosquito.

Stilt Bug

Stilt Bug

Hi Lizzie,
At first we thought this might be a predatory Thread Legged Bug, but we quickly realized the antennae and front legs are very different.  We quickly matched your adult to a Stilt Bug on BugGuide and we learned on the BugGuide information page that:  “Hosts include Oenothera biennis, Gaura, Panicum, tomatoes, sometimes ornamental gourds.
J. spinosus is in part predatory (survival much higher when animal food is available).”  So it appears to be a partially predatory species that also feeds on ornamental gourds.

Thank you! I appreciate the identification. I adore your website and its lovely insect photos.

I recently sent a few pics of insects I’ve found in Northern Indiana. I have been able to ID it with Peterson’s Field Guide, and then confirmed it with pics on BugGuide. They are stilt bugs (the Berytidae Family). Just thought I’d let you know so you don’t spend a lot of time searching for it.

Mating Stilt Bugs

Hi Vince,
Thanks so much for resending your photograph and identification.  We apologize, but your first attempt slipped under our radar and we never saw the letter.  We are very excited to have this image of mating Stilt Bugs because the family Berytidae was not represented on our site until your letter.  According to BugGuide members of the family can be identified because:  “Antennae have four segments, the fourth enlarged.

Not sure about this bug
I thought it was some kind of walking stick, but someone said to me it was more of a true bug. I am perplexed now as I haven’t found anything like it in various books for insects in our area. I thought it might be a North American walking stick but I realize it is way too small for that. I caught those two lovebirds in my backyard in Beloeil, Qc, Canada. The berries will give you an idea of their size. If you can give me a pointer in some direction on this one? Thank you for your lovely site!

Hi Frederic,
These are mating Stilt Bugs, not the Thread Legged Bugs we originally thought when we wrote back to you. Stilt Bugs are True Bugs in the family Berytidae. Some species are predators and others feed on plants according to BugGuide. We are very happy to post your images since this is a new family for our site.
