Anna Lena Phillips in American Scientist:
Last spring, the periodical cicadas emerged across eastern North America. Their vast numbers and short above-ground life spans inspired awe and irritation in humans—and made for good meals for birds and small mammals. Such snacks do not come without cost, however: Cicadas emit extremely loud shrieks when captured. Perhaps the pattern of the giant silk moth Citheronia azteca (right) evolved to resemble a cicada as a form of Batesian mimicry—imitation by a nonpoisonous species of a poisonous or unappetizing one. So Philip Howse speculates in Giant Silkmoths: Colour, Mimicry and Camouflage (Papadakis, $40 paper), in which he and photographer Kirby Wolfe showcase these members of the Saturniidae family.
Wolfe offers notes on collecting and raising silk moths. But the book’s wealth of photographs serves as collection enough: Viewing page after page of stunning moths from all over the world, I felt the guilty pleasure of seeing more of these creatures than one would ever normally encounter. Caterpillars are well represented also.
