They just go kind of dormant. They land on something and sit till it warms up. Their metabolisms are hugely driven by ambient temperatures.
Wherever their senses tell them the good eating is.
Correct, and I dont think they actually need to mate.
I would. I actually ate some porkchops that sat on the grill for a few hours. Then I noticed the seasoning was wiggling. Yuuck.
There are species of flies that bite and they appear in the states as far as I know. Here in Canada our flies cannot overwinter so they actually colonize yearly from farther south. I’ve never been bitten: no huge population of biting flies here.
We have the same horse flies.
A) you cant see them, they are dark. B) they are barely active, sluggish. Unlike moths they dont congregate around light sources. Unlike mosquitos, they dont home in on the CO2 exhaled by humans. So they are there, you just dont notice.
As a Doper, you have an obligation to try to tell her the truth, and as an uncle, you have an obligation to try to gross her out. When they land on her food, they’re regurgitating a small amount of liquid to dissolve the surface of the food, then slurping that back up to feed (incidentally, they taste the food with their feet). And when thinking about the composition of this liquid, remember all the other things flies like to eat. They’ll do this pretty much every time they land on food, but they’ll only lay eggs if they’re undisturbed (and, of course, if they’re female and have already mated). They’ll generally lay their eggs in high-protein foods like meat, though they’ll also eat sugary foods. The eggs, if they lay them, hatch into maggots, and the maggots turn into adult flies in much the same way that caterpillars turn into butterflies.
to be fair, technically what Fuzzy said was “I don’t think they actually need to mate”, not “I don’t think they actually need to mate in order to reproduce”, so there could be lots of flies in convents or such
Excuse you. I did not proclaim NO biting flies, just not a huge population of them. No more than the states in any case. What I said is that I have never been bitten(in 38 years). Are they common enough that you need to take preventive measures to avoid them? I’m guessing not.
And mosquitoes are neither flies, nor particular to Canada.
Apropos of not a lot, my “favorite” North American Biting Fly. Those big-ass fuckers can actually draw blood and they hurt. I’m normally quite blase about stinging and biting insects, but I’ll actually squeal like a little girl and do a little dance to avoid being nailed by one. They even have the absurdly appropriate scientific name of Tabanus punctifer.
