Twilight Hue
Twilight, not bright nor dark, good nor bad.
I think Flys are villianized a little too much although they can and do transmit diseases and the like.I recall many years ago, for a period of a few days, I was incessantly menaced by this insufferable fly. It would fly and buzz right in my ear when I was trying to sleep, especially in the early morning. I tried to go after it with a fly swatter a number of times, but unsuccessfully.
Apart from that, They keep themselves very clean actually and are definitely amazing insect aviators.
The maggots albeit disgusting, are very useful when it comes to breaking down filth and even have a medical benefit of removing gangrene from severe infected wounds.
One thing though is they smell horrible but it's a givin considering what they like to land on and eat which is why they are a pest in people's eyes.
