Life in the Soil
is one of those rare books so chock-full of information that I can't
really hit even the highlights in a lunchtime series. So today's
post includes some tidbits too good to skip, but which don't fit into a
cohesive post.
The
most common insects in soil are usually a combination of ants, mites,
springtails, beetles, and fly larvae, with the winner depending on the
habitat. You might not have heard of springtails, but chances are
you've seen them if you live in a climate with cold winters. These
tiny insects look like black dots hopping around on top of melting
snow, having come up out of the ground to escape the inundation.
Dung
beetles and flies are in constant competition for high-quality
herbivore dung. (Carnivore dung just isn't as sought after.)
So dung beetles hedge their bets by carrying around tiny mites.
As soon as the dung beetle hits a new cow pie, the mites jump down and
go in search of fly larvae, which they kill and eat. Once the cow
pie is used up, the mites hop back on board their beetle partners to
ride to the next patch of dung. (This makes me wonder if you could
cut down on fly populations in pastures by somehow encouraging the
mites and dung beetles?)Is your appetite
whetted? There are many other fascinating tidbits in Nardi's book,
so this is definitely one you'll want to check out on your own.
