Field Guide to Butterflies of South Dakota

Book excerpt: The defination of butterflies and a general discussion of them, and a description of the physiography and climate of South Dakota (with color illustrations of the landscape) is followed by reports on 177 butterfly species found in South Dakota, listed by families. Each report consists of the common and Latin names; short sections on description, similar species, distribution and habitat (including a shaded map of counties of distribution), early stages, larval host plants, adult energy sources, flight period, and general comments; and prints from photographs showing (at least) an upper view of a male, one of a female, and an under view of one. The end material includes a checklist of South Dakota butterflies, a butterfly calendar, and a hypothetical list [butterflies which might live in the state, but which have not yet been recorded].
