The Geometridae (Lepidoptera) of the Galapagos Islands. American Museum novitates ; no.2510

Abstract

"The moths of the family Geometridae are represented in the Galapagos Islands by a relatively small number of species; only three were recorded in the literature prior to 1970. The number now stands at 13, with one of these being an unidentified species. Of the remaining 12, nine are endemic to the archipelago; the other three are common, wide-ranging species that occur throughout most of the New World. It is postulated that most of the geometrid moths were carried to the islands by winds; a few may have been introduced by man. Descriptions and keys for the adults, and male and female genitalia are given for the identified species; they are also illustrated. Brief early stage notes and food plant records are given when known. Perizoma (?) perryi and Semiothisa cruciata isabelae are described as new"--P. [1].
