10. Northern Cicada Species

This guide covers all the species of cicadas reported from Canada and adjacent USA of which 20 occur in Canada and 25 others are reported from adjacent areas, or are accidentally imported. Regional guides are available for several areas of the southern USA, and these (although mostly badly out of date and difficult to use) present 16: species of the southeastern states Footnote 1, 22 species from Kansas, 11: from New Jersey, 65: from California Footnote 2, 10: in Michigan Footnote 3, and 27: from Colorado Footnote 4. A selection of 33 Arizona cicadas is available online.

There are 45 species recognized today from the northern USA and Canada, but some of these may prove to be local hybrid swarms. A check list (Section: 10A) of the scientific names (including synonyms) is provided so you can find out what species to expect in your part of the country, if you live in the study area. The identification guide begins with the genera (Section: 10B) and this leads you to the various species under each genus.

Males and females may be distinguished by the structures on the underside of the abdomen. Males have well-developed auditory organs which are either exposed ear drums or "tympana", also called "mirrors" (M, below the tymbals, T) or are hidden behind flaps (opercula); females have a prominent egg-laying process (ovipositor) folded into the conical end of the abdomen.
