about two weeks ago it was -25C for days. I mean air snappin' cold. The
ground was solid as a rock. A warm front comes through and the temp shoots
up to +3C and I'll be damned .... I saw a mosquito.

Hmm. Well mosquitos spend most of their lives as aquatic larvae.
Presumably not all the watercourses in your area froze solid to the very
bottom?
I presume you terminated it with extreme prejusdis? ;-)

Don't know about spiders, but insects employ two strategies that I know of.
One is to burrow into the ground below the frost line. The other is to
replace their blood (hemolymph) with a substance with a much lower freezing
point than water (glycerol?).
Right about now the skunk cabbages are getting ready to bloom. They are able
to melt the snow and ice around their flowers by generating mass amounts of
heat.

Mother nature is pretty amazing isn't she?
I saw a piece on a very small tree frog that borrows into ground and it's
actually frozen there until the spring thaw.
The opposite end of the spectrum ... those tube worms living near those
volcanic vents at the bottom of the ocean.
Like I said life is an unstoppable force.

Amazing... terrifying... one or he other. (My mum is still creeped out
by the 4-foot millipede that catches and eats live bats.)

Yeah. I think that's the Andean frog I mentioned.
It's cells have antifreeze, and the intercellular space has a chemical
which *prmotes* freezing. The net result is that the space between the
cells freezes, but the cells themselves do not. In essense, the animal
becomes a colony of single-celled organisms for a few months.

There are bacteria that live *in* those volcanic vents, never mind
"near" them. ;-)

Umm. No thanks. I'll pass. Thanks for offering though.

The one I saw was from NE US .... Maine I believe. I saw it on Jeff Corwin.
Cool!! .... same thing from two diff species in two diff places.

Number three is to lay eggs and die, and let the eggs hatch in the spring.
The egs, being much simpler, don't have the same problems. (Or maybe just
have less water in them or something.)

Or a lower surface area to insulate. ;-)
