Part of the website called:
Singing Insects of North America (http://entnemdept.ufl.edu/walker/buzz/index.htm)
Most of the pages in Singing Insects of North America [SINA] are either taxa pages (for example, species pages, genus pages, subfamily pages, and family pages) or image pages. Image pages display the "regular" version of an image (see Image views), describe the image, and give its source. They are usually accessed from thumbnails of the image on a taxon page. Other types of pages are pictorial key pages, checklist pages (accessed from "List of species" buttons), and general information pages (such as this one).
