Fly Group Behavior
When i went outside this morning there were about
100 flies on the wall of the shed. They were also in a metal bucket
about 3 meters away and my ashtray. They were not flying but
crawling around and as other bugs came up out of the ground and
started to eat them, the flies who were slowly moving didn't put up
a fight. What could have been going on?
This seems like a strange situation. The only thing I can think of is that
the flies hatched out early because there were a few warm days. They were
staying on warm things like the shed and the metal bucket, things in the sun
or that retained heat. It is common for flies to stay fairly still when they
are too cold. I'm thinking they hatched out too early, got too cold and were
trying to warm up, and were not able to fly away from the other insects.
