The primary goal of this Web site is to help users identify all species of crickets and katydids from America north of Mexico and the common species of Florida cicadas. The males of most species in these groups 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.
|Those who have not used SINA before should be advised that the morphological keys have not been updated to accommodate some of the changes made in the higher classifications of crickets and katydids since 2001. Those who have an idea of the common or scientific name of the species they wish to identify, should go directly to the list of species of North American crickets or katydids. There they will find direct links to the “species pages” of the 133 species of crickets and 262 species of katydids arranged under their current higher classifications.|
|To accomodate most browsers, SINA serves audio files as MP3, OGG, and WAV files. Most browsers support MP3 and/or OGG files and, though these are compressed files, under most circumstances, audio quality is almost as good as WAV files (which are not compressed). If you experience poor sound quality, try opening the web page in another browser.|

Noteworthy aids to using SINA
Current update of SINA
SINA is designed to be used without requiring the user to consult detailed directions. At first, when these instructions were written, SINA was not as user friendly as it is now. The text below is lightly edited and left in place—in case some user cares to read it.
Go to How to recognize crickets, katydids, and cicadas.
Go to the division dealing with Crickets, Katydids, or Cicadas and click on the Keys button. When you must decide among the species within a genus, seek advice or help on the genus page. Then browse the species pages and accept or reject the choices on the basis of appearance, song, morphological features, and geographical, seasonal, and ecological distribution.
Go to the division dealing with Crickets, Katydids, or Cicadas and click on the List of Species button. In the checklist, find the species (by scientific or common name) and click on the link.
Go to the appropriate division (Crickets, Katydids, or Cicadas) and click on the List of Species button. Within the checklist, find the genus or subfamily (by scientific or common name) and click on the link.
Go to the subfamily page (from the key to subfamilies or from the List of Species). The first section of the subfamily page will have a link to the key to genera.
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).
SINA has dark-green buttons and gold buttons that facilitate rapid movement to and from every part of the site. The dark-green buttons, at the top of most pages, take the user to the major divisions of SINA. The gold buttons, at the bottom of species pages and at the top of most image pages, are for local moves. The text on each button identifies its action. "Next Species" and "Previous Species" buttons move the user from species to species in the same (alphabetical) order as in the checklists. "Next Image" and "Previous Image" buttons move the user among images of a species in the same sequence as they occur in thumbnail views on a taxon page.
Most images can be viewed in three sizes: thumbnail (128 pixels wide or less), regular (usually 640 pixels wide), and jumbo (usually 1280 pixels wide). To move up the scale of magnification, click on the image. To move down from a jumbo view, use the Back function of your browser. To move down from a regular view, use the appropriate local navigation button.
Most links on this site are internal—that is, they go to items that are posted as part of SINA. Links that go to items that are not part of SINA are identified by the text for the link being a URL. For example, here is an external link to the online version of the Orthoptera Species File: http://orthoptera.speciesfile.org . And here is an internal one to How to use SINA.
All references in SINA are now listed both in a union list and in at least one subject-specific list of references. The subject-specific lists are on the pages for particular SINA subjects, usually subfamilies or genera. This places the most relevant references for these subjects in a place where they can be browsed efficiently. The union list is primarily to provide an efficient means to determine whether a known reference is available in full text on this site. More than 250 of the more than 650 listed references are so available, usually in the form of PDF files made by scanning articles or reprints.
Citations to literature in the text of SINA are made by the name-year system (e.g., Walker 1974). Each in-text citation is linked, as in the example just given, to an entry in a list of references. Each entry specifies the item of literature in enough detail to permit its retrieval from a library that holds it. In some cases the entry is linked to the full text of the item in PDF format.
The PDF document "Coding system for SINA files" explains how SINA's more than 10,000 files are named.
We hope you have found (or will find) Singing Insects of North America useful. We encourage you to help make it better. Here are four ways you might do so.
Contribute good photographs of living individuals for species for which SINA has none.
Contribute photographs of living individuals that are better than the ones currently posted on SINA.
Contribute good recordings of the calling songs of species for which SINA has none.
Point out errors and suggest improvements.
If you wish to contribute to SINA in any of these ways, please contact the current editor at email@example.com.

Piotr Naskrecki encouraged us to make an interactive Web site that could be distributed via CDs rather than merely make audio CDs of the songs of North American insects. The CD accompanying his Katydids of Costa Rica inspired us to begin this project, and we have shamelessly copied, with his approval, many of the devices that make his CD so compelling.
During more than 40 years of studying crickets and katydids in North America, indoors and out, I've been helped in large ways and small by more persons than I can remember. The ones listed here are among those who deserve special credit.

SINA was founded with the intent that it be, and remain, openly accessible to all with minimal restrictions on the use of its contents.

Website: Songs of Insects
This is an easy-to-use, beautiful website for learning about the common species of singing insects in the eastern United States. Its photographs are of professional quality as are its sound recordings and the displays of their audiospectrograms.
Identification manual: Field Guide to Grasshoppers, Katydids, and Crickets of the United States.
About the manual. Tips for using SINA to supplement the Field Guide's treatments of katydids and crickets. Listen to sample songs.
As the present update of SINA continues, there will be occasions when the current draft of the ongoing update of its styles and content will be of interest to some particular group. For example, the faculty of the Entomology and Nematology Department of the University of Florida should be given the opportunity to learn something about the ongoing update of SINA as Tom Walker and Teresa Cooper work on it in Rooms 2104 and 2115 of Steinmetz Hall.
This is the current draft of an ongoing update of Singing Insects of North America [SINA],
edited by Tom Walker with able assistance from Dr. Teresa Cooper [Dr. Cooper has these entomological papers to her credit.]
The goals of SINA are described in its first two paragraphs. You are invited to browse any and all parts of SINA, but in case you have no time for browsing, here are links to five foreign species that have invaded Florida and an item of interest about each one:
Japanese burrowing cricket (Velarifictorus micado) (item)
Lychee bush cricket (Xenogryllus unipartitus) (item)
Woo’s katydid (Phaneroptera nana sp. #2) (item)
alien raptorial katydid (Phlugis sp.) (item)
Archbold alien katydid (Alloteratura? sp.) (item)
