Clearwing Moth

Dear Rochelle,
This is not a Bee, but your mistake is understandable.  This is actually a Clearwing Moth in the family Sesiidae, and many members of the family are very effective Wasp mimics.  We believe this might be an American Hornet Moth which is pictured on BugGuide, and the long ovipositor indicates this is a female.

Your letter to the bugman:  Can’t find this on the web. Can you identify it? It is on a south facing Passion flower.
Thanks,

Large Red-Belted Clearwing

Dear GT,
Though this looks like a Wasp, it is actually a Clearwing Moth in the family Sesiidae, and many members of the family benefit from mimicking stinging insects like Wasps.  We quickly identified your Large Red-Belted Clearwing,
Synanthedon culiciformis, on UK Moths where it states:  “The moth flies earlier in the year than many other clearwings, being on the wing in May and June.  The species inhabits heathland and woodland, where the host tree, birch (Betula abounds, and is known from much of mainland Britain.”  The site also states:  “Although generally larger than the similar Red-belted Clearwing, the sizes overlap and it is more easily distinguished by the orange-red suffusion at the base of the forewings” and that color is not evident in your images, so we would not rule out that your moth is a Red Belted Clearwing, Synanthedon myopaeformis.  According to UK Moths:  “The moths fly during the day but are not often seen, except by the use of pheromone lures. They occur from June to early August.”  Though the “orange-red suffusion” is not evident, we still believe your individual appears more like the former species.

Strawberry Crown Moth on Cannabis

Dear DB,
This is one of the Wasp Mimic Moths or Clearwing Moths in the family Sesiidae.  We believe we have identified it as a Strawberry Crown Moth,
Synanthedon bibionipennis, thanks to images on BugGuide.  Were there strawberry plants nearby?  According to BugGuide:  “Larvae bore in the roots near the crown or in the stems near the base of various species in the Rose family (Fragaria, Rosa, Rubus, Potentilla). Considered to be a pest of strawberries. Adults take nectar from many different flowers.”  Since Cannabis is not in the Rose family Rosaceae, we suspect your plant is safe from this Strawberry Crown Moth.

Your letter to the bugman:  I found this beauty while visiting a local lake in 2017.  It didn’t attempt to fly away the entire time we were there, and seemed unfazed when I stuck a phone camera several inches from its face.   I was afraid it was dead, but it was still moving a bit.  Thank you!

Your letter to the bugman:  I found this wasp-like bug at Panorama, BC. Its tiny head and almost moth-like antenna made me stop and look again. I wish I knew what it was. It did not move while I studied it, but I also did not want to disturb it as I don’t know if that’s a real stinger or if its a copy-cat! I saw it the second week of August.

Your letter to the bugman:  Hello,
Found this guy chilling on the shaded wall of a building, so still I thought he may have been asleep. 90+ F outside, so maybe he/she was just lethargic. We are in an industrial area of town near slow-moving swampy backwaters of the Columbia River, so it is a very entomologically active place. Spider wasp maybe? But so brightly colored!
