I saw some type of large fly larvae in my BSF container a few days ago, but I'm not certain that they're BSFL. I've seen Black Soldier Flies laying eggs, but there has also been another insect visiting the scraps that may be a fly. The larvae I'm seeing look very similar to BSFL, but I have a gut feeling that they aren't. I have some photos of the unknown insect and I'll do some research into it.

Regardless of what this other insect is the BSF will eventually take over the scraps.
