Singing Insects of North America: SINA audio

Singing Insects of North America (SINA) is a unique resource providing extensive content covering the crickets and katydids (and, to a much lesser extent, cicadas) of North America north of Mexico. This content includes audio recordings, images, text, and identification keys. SINA was created and is still maintained by Dr. Thomas J. Walker of the University of Florida, a pioneer and leader in the study of North American crickets and katydids beginning in the late 1950s and continuing into the 21st century. <p></p>http://entnemdept.ifas.ufl.edu/walker/Buzz/
