Singing Insects of North America (SINA)

Thomas J. Walker, founder of SINA          Teresa Marie Yawn, editor, webmaster

The primary goal of this website is to help users identify all species of crickets and katydids from America north of Mexico. The males of most species in these two taxa make loud, persistent calls that attract sexually ready, conspecific females. Because the songs are loud and species specific they are usually an easy means of identifying the caller. They also facilitate field and laboratory studies of many sorts.

Secondary goals of this site are to attract amateur and professional biologists to the study of singing insects and to provide them helpful information and access to relevant literature.
