Subject: What can be this “larva”?
Geographic location of the bug: Madrid city, NE
Time: 01:59 PM EDT
Your letter to the bugman: There are lots of this larva (I think that it is a larva, but not sure, perhaps a chrysalis) at my parents flat roof. Many of them near to an open box with compost. Some of them looks alive, some of them are “emtpy”. It is the first time that something like that appears there.
How you want your letter signed: Chris
These are Black Soldier Fly larvae and they are often found in compost piles. They are harmless and are actually considered beneficial as they help to break down the organic materials in the compost pile.
