Grasshoppers, Crickets, and Katydids

 
Order Orthoptera

Orthoptera is the order of insects that is characterized by having long hind legs, modified for jumping; leathery forewings; unsegmented cerci (appendages at tip of abdomen); small and well separated hind coxae; a pronotum with large descending lateral lobes; hind tibiae with two dorsal rows of teeth; and nymphal wing rudiments reversing their orientation in later instars. The order includes grasshoppers, locusts, crickets, and katydids.

There are about 20,000 species worldwide, 1,200 species in about 256 genera in North America north of Mexico.

Camel cricket (Ceuthophilus sp.)
   

This is a very common genus of native crickets. It can be found under rotten logs, under stones, in mole hills, and other moist dark places, but is most often encountered in basements. Unlike most crickets it has no hearing organs (tympanum).

The family (Rhaphidophoridae) is identified by its distinctive, hump-backed shape, lack of wings and tympanum, and antennae longer than the body. The genus (Ceuthophilus) is identified by four end segments (tarsi) on each leg and the lack of a spine on the front of the tibia of the foreleg.

Curve-tailed bush katydid
   

This may be the most common large bush katydid. It is found from spring to autumn feeding on leaves and tender stems of a variety of plants. The head, body, wings, and legs are pale grass green, making it difficult to see except when it is startled into flight.

Capitalization of Common Names

Insect scientific names are governed by the International Commission on Zoological Nomenclature (ICZN). Vernacular (common) names are not. In an attempt to “assure the uniformity of (common) names of common insects” the Entomological Society of America (ESA) published Common Names of Insects and Related Organisms. ESA has no rule or guideline that addresses capitalization of common names. However, the database of common names published by ESA does not capitalize common names. National Center for Biotechnology Information (NCBI) also uses uncapitalized common names. Most other sources, including ITIS, BAMONA, Odonata Central, and the Peterson Field Guides, capitalize common insect names. MinnesotaSeasons.com will adhere to the convention followed by ESA and NCBI.
