Going Buggy In The Desert.
By Gregory McNamee
TO JUDGE BY this graceful study of insects and desert plants,
John Alcock, a professor of zoology at Arizona State University
and prolific writer about Sonoran Desert ecology, is a suburban
neighbor's worst nightmare.
First, he relates in the opening pages of In a Desert Garden,
he replaced his Bermuda grass lawn with gravel, cacti, and succulents
to replicate what the desert around Phoenix looked like before
humans remade it. Next, he festooned his yard with cowpies carefully
selected for size, weight, and dryness, "the crème
de la crème of termite chow, as far as Gnathamitermes
are concerned." Then he seeded his property with flowers
to attract a flotilla of winged and crawling creatures, "carpenter
bees and globe mallow bees, brittlebush aphids and milkweed aphids,
these and many other insects." Thus equipped with a backdoor
laboratory for ecological studies, Alcock spent the next few years
observing what happened.
Alcock fills his pages with asides on the insects he's studied
for so long at close hand. We learn that female praying mantises
have gotten a bad rap as spousal murderers; rising to their defense,
he observes that "the extent of female consumption of males
during copulation had been greatly exaggerated." (Whew!)
We learn as well that aphids are to be prized, the occasional
loss of a rose bush or milkweed plant aside, for their marvelous
properties: They reproduce "without the curious beings we
call males," and otherwise develop and mutate in unexpected
ways.
He may not convince you to invite termites into your home or
strew your own yard with cowpies, but Alcock does a fine job of
revealing the role of insects in the environmental workings of
the desert.
