Summer is here and my area seems to have an excess of flies. I can’t go on a hike without them buzzing all around me and trying to land on me. What do they want?? Sweat? There is plenty of water elsewhere. Can someone explain so I can figure out a way to dispel these demons?
In: Biology
What I want to know is how do house flies know when I just temporarily opened up my front door for a minute? I mean are they waiting around outside with an eyeball on my door just waiting for the opportunity? Or are there so many of them around at all times (even though I can’t see them anywhere) that somehow there’s always one nearby when I open the door? And like, I was under the impression that they don’t have very good eyesight so I don’t know how a fly that’s twenty or thirty feet away sees me opening the door.
And yet despite all that somehow… I open the garage door or the back door or whatever… And 10 seconds later there’s a big old fly in there.
How do they do it???
