Fauna of Orthopteroidea (Orthoptera, Dermaptera, Mantodea and Blattodea) of the National Park “Smolny”

Abstract

The species diversity of insects from the orders Orthoptera, Dermaptera, Mantodea and Blattodea in the National Park “Smolny” (Republic of Mordovia, Ichalki and Bolshoe Ignatovo districts) was studied. It consists of 44 species: Orthoptera (40), Dermaptera (1), Mantodea (1) and Blattodea (2). For the first time for the Republic of Mordovia, two species are noted – Isophya modesta and Oecanthus pellucens. The most common are Ectobius lapponicus, Chorthippus biguttulus, Euthystira brachyptera. Rare are species confined to areas with sparse herbage (Chorthippus pullus, Dociostaurus brevicollis, Myrmeleotettix maculatus), inhabitants of rich meadows and steppes (Isophya modesta, Poecilimon intermedius, Stenobothrus lineatus), and inhabitants of eutrophic swamps (Conocephalus dorsalis, Stethophyma grossum). Differences in the distribution of two species of cockroaches of the genus Ectobius, two species of grasshoppers of the tribe Chrysochraontini, and three species of bush-crickets (Platycleidini) are described.
