Thank you. Pic of Pselliopus sp.
Just wanted to thank you folks for the great site. After spending alot of time pulling hair searching the web for "orange bug" I found your site and was able to identify the bugs I came across while in the garage. I have included a picture of one of the several Assassin bugs (Pselliopus sp.) I found and identified thanks to your site. Thanks again,

Hi Robert,
Thank you for your kind letter and the photo of a Pselliopus Assassin Bug you contributed to our site.

What’s This Bug?

Hi HarrysAllOut,
We must say we are curious what you are out about. We are also glad that all of our contributors aren’t as thrifty with words as you are of we would not have much of a site. This is an immature Milkweed Assassin Bug Nymph.

Wheel bug mom
Thought you might enjoy this wheel bug that nested near my shop last spring.

Hi Keith,
This is the first photo we have ever gotten of the adult female Wheel Bug with her eggs.

This just in…. not. We found this character on the side of a house in NE Pennsylvania in August of 2000, in the days before we figured out how to focus the camera we had at the time. Never saw another like it. For years we’ve just looked back at the photo and laughed — what could it be? Why did it seem lichen-encrusted? Now, of course, there’s your extraordinary website, so we’re hoping for an ID. Whaddayasay?

Never mind this one. Found it on your site — a Masked Bedbug Hunter if I’ve ever seen one.

Hi again Jim and Sandy,
How nice to see you don’t take all of your great photos in Puerto Rico. Also very happy you successfully identified your Masked Bedbug Hunter on our site.

Praying Mantis NZ
I am in Dunedin New Zealand and I have found a facinating looking Praying Mantis. It is approximately 13 – 15mm long and looks like a mosquito at first glance. The photos do not show it well but the legs are covered in fine hairs, and it has long antennae coming off its tiny head. As far as i knew there were only two types of Mantis in New Zealand, and I’ve never seen anything like this before. Can you tell me what it is?
Chirsty Brett.

Hi Chirsty,
This is not a Mantid. It is a Thread-Legged Assassin Bug, one of the Hemipterans or True Bugs. It looks very similar to the genus Stenolemus pictured on BugGuide. Sasha Azevedo who posted the photos there has researched the following information, but sadly, did not credit the source: “The Stenolemus assassin bugs hunt spiders by aggressively mimicking insects caught in the web.”

Thread-Legged Assassin Bug from New Zealand
Hi Bugman,
In response to your recent poster’s message regarding Stenolemus and aggressive mimicry, I left no source because I gathered information from a few statements and put it into my own words. However, if you’re interested in the link that was used, this is it below. Good luck. 🙂

creepy little red bug
Hey Bugman-
What is this thing called? I think it’s an assassin bug nymph, but I’m not sure what kind. They love my herb garden, and I’ve read that they are beneficial. I’ve been on the receiving end of that nasty proboscis, but if they eat aphids, I guess they can stay! Thought you might like this picture- you can zoom in even closer if you want to- then he looks really creepy!! Love your website!
San Antonio, Texas

Hi Samantha,
After attempting to open your photo file five times, we succeeded. This is an immature Assassin Bug in the genus Zelus. It is probably Zelus longipes, the Milkweed Assassin Bug, that is common in Texas. While Assassin Bugs are beneficial predators in the garden, they will deliver a nasty bite to the unwary.
