In the 80-plus years I have lived on this grand old planet we call
home, I have come to realize that the world of nature is so complex I
will go out among the stars with only a hint of what's really going on.
Take
bot flies for example. These pestiferous little buggers (pun intended)
make life miserable for any mammal they come into contact with,
especially rodents, livestock and humans. Scientists have placed bot
flies into one big family: Oestroidea (OH-est-ROW-eh-dee-ah). The bot
fly is a "true fly" that is, they belong to the order Diptera, which
means, "with two wings." While all the other billions of insects are
flying around with four wings, flies have only two, and a "balancer"
that gives them the remarkable agility to avoid fly swatters and such.
