Hi i found this bug over the summer while volunteering at a camp. These little bugs were all over. They look like a wasp but where the stinger was suppose to be there was fuzz. Because I was a helper to children we named them fuzzy fellas. I held them all the time and they never bit me or stung, just to be safe I didn’t let any of them hold it. These can fly but are pretty calm. I found that the most came out in the late morning, and less than that in the afternoon. I have searched everywhere to find out what theses little bugs are. Help please? Thanks!

Sycamore Borer

Sycamore Borer

Dear Kara Beth,
You are quite brave.  Though they are very effective wasp mimics, Clearwing Moths in the family Sesiidae are quite harmless, though they really do resemble stinging wasps.  Your individuals are Sycamore Borers,
Synanthedon resplendens, a species we originally identified from Encinitas in 2014.  According to University of California Integrated Pest Management System:  “The sycamore borer, Synanthedon resplendens, occurs in the southwestern United States. It is prevalent in sycamore and also infests oak and ceanothus. The male is mostly yellow with a brownish-black head and black bands on its body. Its legs are yellow, except for black along the margins on the portions nearest to the body. The mostly clear wings have orangish to yellow margins. Sycamores tolerate extensive boring by this insect, and generally no control is recommended.”

Female Peach Tree Borer

Dear Ron,
This is a female Peach Tree Borer, a wasp mimic moth whose larvae bore in the wood of peach and related stone fruit trees.  We just posted an image of a mating pair of this sexually dimorphic species.

Mating Peach Tree Borers

Mating Peach Tree Borers

Hi Hillary,
Despite the lack of critical focus, the distinctive markings of these sexually dimorphic, mating Peach Tree Borers,
Synanthedon exitiosa, are quite apparent.  The darker individual in the pair with the bright orange band is the female.  Peach Tree Borers are moths in the Clearwing family Sesiidae.

Hey Bugman,
I saw this bug sitting in my strawberry patch.
What is it?

Squash Vine Borer

Squash Vine Borer

Dear Dov,
Do you have squash or melon plants near the strawberries?  This wasp mimic is actually a moth called the Squash Vine Borer.  The female lays her eggs on the vines of squash and other members of the family and the larvae bore in the stems, often causing the plants to wither and die.  The Squash Vine Borer will not harm your strawberries.

I found this insect, and it looked really cool. I tried searching for what it could be, but I couldn’t find anything! Do you know what this bug could be??

Hello Bugman,
I’ve searching the internet for two hours trying to ID this bug but I can’t find it at all…
I found it in the playground where my 2 year old loves to play everyday but now Im not sure if I should let her play there anymore!
Any help would be greatly appreciated!

Clearwing Moth from Japan

Clearwing Moth from Japan

Dear Paula,
Though we have not been able to determine the species, this is a Clearwing Moth in the family Sesiidae, a family with many members that mimic stinging wasps as a defense.  This individual is not pictured in the Clearwing Moths of Japan pdf we located, and it also bears an uncanny resemblance to the female Peach Tree Borer,
Synanthedon exitiosa,  a species that is native to North America and an excellent example of pronounced sexual dimorphism.  We cannot at this time determine if this is a species native to Japan, or if the North American Peach Tree Borer has been accidentally introduced to Japan.  This moth poses no threat to your daughter.
