Carolina mantis


The Carolina mantis is a species of praying mantis of the subfamily Stagmomantinae.
Sexual cannibalism occurs in roughly one quarter of all intersexual encounters of this species, though specimens of this species will engage in cannibalism regardless of age or gender if the opportunity presents itself.
Carolina mantis oothecae can be purchased in garden supply centers as a means of biological control of pest insects. However, only those labeled as this species should be released because most oothecae sold in the United States belong to the invasive Chinese mantis. It is the state insect of South Carolina.

Stagmomantis carolina is native to South America, Central America and North America. Southern United States, Central-Southeastern United States, Buenos Aires Mexico, Panama, Trinidad, Venezuela, Suriname Belize, Costa Rica, Nicaragua, French Guiana and Guatemala.

Description

Adult females are 47 to 60 millimeters in length while adult males are usually about 54 millimeters in length. First instar nymphs are 7-12 millimeters in length. When the nymphs eat more, their abdomens get much longer. The Carolina mantis has a dusty brown, gray or green color useful as camouflage in certain environments. The Carolina mantis' color varies because the nymphs are able to adjust their color to match the environment they are in at the time of molting. They can adjust their color over each molt, if necessary, until they reach their final molt to adulthood. An unusual trait is that its wings only extend three-quarters of the way down the abdomen in mature females; this trait is also seen in Iris oratoria, which can be distinguished by the large eyespots on the hind wings of both adult male and female Iris oratoria. Both adult male and female Stagmomantis carolina have a dark-coloured dot on each of their forewings, which may be partially hidden in a brown or dark colour morph individual.

Synonyms

The species was first described in Centuria Insectorum as Gryllus carolina.
