Geometer Moth (Pterotaea crinigera)

Arthropoda > Insecta > Lepidoptera > Geometroidea > Geometridae > Ennominae > Boarmiini

Endemic to the Channel Islands, with records from San Clemente and Catalina Islands, and a mainland record from Palm Desert in Riverside. The moth resembles a darker P. crickmeri, with shorter, broader wings and long pectinations on the male antennae (~2mm), and mostly indistinct maculation; forewing and hindwing similar. Because the species was described from a single specimen, I can't say with certainty that the moths pictured here are indeed this species. Photos I've taken on Catalina Island seem to show a great deal of intraspecific variability, but due to a lack of material to compare to it is impossible to say whether these represent natural variation within the species or if these photos represent a different species altogether.
