Overview

Brief Summary

The Oblong-winged Katydid (Amblycorypha oblongifolia) is found in the eastern United States west to the Great Plains, but is absent from southeastern Georgia and most of Florida. It is found around the edges of freshwater and salt marshes, in wet and dry meadows, in shrubby fields, and around forest edges.

The stridulatory area of the male exceeds the area of the pronotal disk (males of the three species most similar to the Oblong-wing in its range have stridulatory areas approximately equal to the area of the pronotal disk). Although normally green, pink individuals are occasionally encountered.

This katydid, which is 42 to 52 mm in length, is the most widely distributed of a group of four Amblycorypha species that exceed 40 mm in length and have relatively broad forewings (length 3.1 to 4.0 times maximum width). The other widely distributed species in this group, A. carinata, has angular lateral edges to the pronotal disk and, at least in the northeastern U.S., tends to occur later in the season than the Oblong-wing.

Eggs of the Oblong-winged Katydid are laid in the soil and, at least in the northern part of the range, may require two or more years to hatch. There is a single peak of adult abundance each year, with the earliest dates ranging from late June to mid-August, depending on latitude.

The calling song is a "zi-zit" that may be repeated several times.

Amblycorypha oblongifolia

The Oblong-Winged katydid (Amblycorypha oblongifolia) is a species of katydid, or bush-cricket, of the family Tettigoniidae (long-horned grasshoppers).

Appearance[edit]

The color of the Oblong-Winged katydid is either green, tan, pink, or a dark tan or orange. Green is the most common amongst this species of katydid. Pink and tan are rare, but dark tan or orange is very rare. The origin of the unusual color stem from genetics, not from gender, age, or environment. The color is apparent from birth, and throughout their life.

Color variations
The most common morph, having a green color 
Pink being the more rare morph. 
The rarest morph, having a dark tan or orange color. 

Distribution[edit]

The Oblong-Winged katydid is common throughout the northeast of North America, but also can be found to the midwest.
