Although I probably would
have gone with the wait-and-see approach, Mark opted to spend an extra
$20 on some black-soldier-fly eggs to get our bin
off to a faster start. This was probably a good idea since summer
is already waning and we'd like to get some data on the composting
experiment before winter.
Meanwhile, an expert over at Bugguide.net provided some information on the yellow soldier flies that I posted about yesterday.
Fly expert Martin Hauser noted: " While [the black soldier fly] eats
literally everything (it is used in organic waste
disposal), [the yellow soldier fly] develops also in my compost pile,
but they clearly
prefer rotten fruit." It sounds like if we had enough excess
squash and other semi-sweet morsels, we could expand our bin's capacity
with this second species too. In fact, I wouldn't be surprised if
yellow soldier flies end up laying eggs in many black-soldier-fly bins
undetected.
