, from which it differs in its in male song pitch, female song pitch preferences, abdomen color, and mitochondrial DNA. Both M. tredecim and M. neotredecim are closely related to the 17-year species M. septendecim
, which was identified by Linnaeus in 1758; these three species are often grouped together under the name decim periodical cicadas

The underside of the abdomen of M. tredecim is light orange or caramel colored, lacking the dark bands seen in M. neotredicim and M. septendecim.Habitat, distribution, and cicada "broods"
Magicicada species occur across the southeastern United States. M. tredecim was the first to be described of the four species with a 13-year lifecycle. It has been observed in all of the three extant broods of 13-year cicadas: Brood XIXBrood XIX
Brood XIX is the largest brood of 13-year periodical cicadas, last seen in 1998 and reappearing in May and June of 2011 across a wide stretch of the southeastern United States...
