Mating Wheel Bugs

We must thank you for cheering us up with your kind letter, and also because though we do not believe your image documents typical Wheel Bug mating, we are nonetheless thrilled to post it.  Probably the greatest reason your letter cheered us is that we just made a Wheel Bug posting Bug of the Month for October, but there is no reason we cannot add a second Bug of the Month posting for October, but with a more positive outcome for the Wheel Bugs.

Thank you, that was a strange bug!! And its not typical? I don’t know much about bugs, lol. However i did see one more picture of that bug with two of them on its back and it was called something like a mating frenzy haha.

Your letter to the bugman:  I found this little guy on a plant I recently brought back inside because of cool weather.  Isn’t it a little late in the year for new hatches?

Immature Zelus Assassin Bug

Dear Jennifer,
This is not a Walkingstick.  It is an immature, predatory Assassin Bug in the genus
Zelus.  Handle with caution.  They bite and the bite is allegedly painful, but not considered dangerous.

Your letter to the bugman:  Please help ID this bug. I’ve been having welts and now an allergic reaction, and I found this bug in my sheets this morning. Need to know if it’s a kissing bug or masked hunter…or other assassin bug. I collected the bug if you need more pics I can provide them. Please help. Scared about Chagas’ disease. Thanks

Western Blood-Sucking Conenose Bug

Dear JRN,
The bad news is that this is a Western Blood-Sucking Conenose Bug which is pictured on BugGuide.  The more comforting news is that this is a North American species, and according to BugGuide:  “Bite can cause severe allergic reaction in humans. Bite and defecation into bite can transmit Chagas disease, caused by the protozoan
Trypanosoma cruzi. The North American species can carry the parasite but they do not normally defecate at the site of bite, and thus rarely transmit the disease (Vetter 2001). Rare vector-borne cases of Chagas occur in the so. US (CDC 2013).”

Thank you! This is comforting :).  I appreciate your time and expertise.
Have a great day!

Your letter to the bugman:  Can you help us ID this beautiful bug? We found it on our porch today—a hot and humid August morning in the Southwest Mountains of Virginia. The bug was about 1.5″ long.

Bark Assassin Bug

Dear Amber,
In searching for links to identify your Assassin Bug, we stumbles upon Beetles in the Bush where it is identified as:  “what must be North America’s most beautiful assassin bug, 
Microtomus purcis.”  The site also states:  “Sometimes called the “bark assassin bug”, this species is not quite as large as the better known “wheel bug” (Arilus cristatus) but makes up this by its spectacular coloration—black with the base of the wings prominently marked creamy-white and parts of the abdomen and hind legs bright red. One would think such a conspicuously  marked assassin bug with a bite powerfully painful enough to back up its apparent warning coloration could brazenly venture out during the day with little to fear. To the contrary, this species seems best known for its habit of hiding under bark during the day and venturing out only at night, during which time it is sometimes attracted to lights (Slater & Baranowski 1978, Eaton & Kaufman 2007). A majority of BugGuide photos of the species also mention finding them under bark or apparently attracted to lights.¹”

Your letter to the bugman:  I get lots of interesting pollinators on my mint plants, but these are ones I’ve never seen before, and wonder if you know what they are? Smaller ones we black/dark brown and yellow, the were some busy couples too. Females were much larger and were lighter colors… One was almost turquoise and beige. Thanks for any light you can shed!

Ambush Bug

Dear Jeannie,
This is an Ambush Bug, a member of a subfamily of predatory Assassin Bugs.  Ambush Bugs are quite well camouflaged on greenish to yellow flowers including Goldenrod, and they often wait on blossoms for pollinating insects to ambush and prey upon.  We hope you continue to allow them on your mint despite the bees, butterflies, pollinating flies and wasps that they prey upon.

Recently Metamorphosed Wheel Bug

Dear Joyce,
This is an adult, but freshly metamorphosed Wheel Bug.  When its exoskeleton hardens, this Wheel Bug’s color will be dark gray.

Got it!!! There was a dark grey one next to it.  Thanks so much!
