Good morning, Bugman.
We discovered today a large area of rot on the base of our coral tree. Excavating the rot, I found several communities of this grub pictured. The animals seemed at first not to move at all, but after some time, it became evident that they do move, very slowly.
I am inclined to believe that they are taking advantage of the rotted wood, and are not the cause of it.
They were surely not expecting this sudden exposure!
Can you identify them?

Black Soldier Fly Larvae

Black Soldier Fly Larvae

Dear Swami,
We are nearly certain these are Black Soldier Fly larvae,
Hermetia illucens, which you may find pictured on BugGuide.  Black Soldier Fly larvae are frequently found in compost piles, where they are beneficial as they aid in decomposition.  According to BugGuide:  “Commercially distributed for composting” and “Larvae live in compost, dung, rotting vegetation.”

Dear Daniel,
Thanks so much for getting back to me. Yes, I agree the larvae match the images of Black Soldier Fly larvae on your website.
I am hoping we can save our tree; it seems to be infected with some kind of rot that turns the wood right under the bark to mush. Apparently these larvae love it, as there are quite a few.
Best wishes,

Black Soldier Fly

Black Soldier Fly

Dear Chip,
We actually believe that even though your image does not show the clear areas of the abdomen that are responsible for the common name of Window Fly, that this is a Black Soldier Fly,
Hermetia illucens, because of the white tarsi on the legs, which are evident in this BugGuide image.  Black Soldier Fly larvae develop in compost piles, and a nearby compost pile might have some relevance to the sudden appearance of Black Soldier Flies in your home.  Black Soldier Flies do not bite and they are considered harmless.

Hello,
I noticed this interesting horsefly-like bug laying these green eggs on our car mirror in late spring (June 14th) in Huntsville Ontario. I was hoping you could help identify? It seems like a horse fly, but the eggs are green rather than milky white as many sites have suggested they would be. I wondered if it was a bee at first? I appreciate any help.
Thanks!

Ovipositing Soldier Fly

Ovipositing Soldier Fly

Dear Matt,
We believe we have correctly identified your ovipositing Soldier Fly as either
Stratiomys adelpha or Stratiomys discalis based on images posted to BugGuide.  According to BugGuide:  “S. adelpha and S. discalis are very similar and may turn out to be the same species. The taxonomy of the Nearctic Stratiomys is a mess. There are a few easily distinguished species, but several spp. are defined based on coloration which is variable. The male genitalia have never been examined carefully, and they could be helpful. –N.E. Woodley, pers. comm.”

This is a Solder Fly and we believe it is in the genus Hedriodiscus based on images posted to BugGuide.  Many harmless Soldier Flies mimic stinging wasps and bees for protection.

Dear Elizabeth,
Thanks so much for submitting your high quality image of a flightless female Soldier Fly from Australia,

Hello
I am curious about what this bug is called. It is on my compost bin in sydney, Australia.
Could you please let me know? If I need to remove it or whether it is fine for it to be around the compost bin.
Thank you in advance.

Black Soldier Fly Larvae

Black Soldier Fly Larvae

Dear Aaron,
These are the larvae of Black Soldier Flies,
Hermetia illucens, and they are frequently found in compost piles where they are beneficial, helping to break down organic substances.  According to BugGuide:  “Wide ranging in Western Hemisphere, also in Australasia, Africa, Japan, Europe. Commercially distributed for composting” because “larvae compete with house flies in manure, compost piles, etc., and may thus be beneficial. Adults are harmless and not known to carry any human disease.”
