The brown cricket is considered to be a pest, especially on fields and sports grounds and around young seedlings. [2] At high densities, they can form large expanses of dead lawn. They are particularly considered to be a problematic species around cricket pitches, where they destroy the carefully maintained lawn. [3]
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. ... are robust brown or black insects. [1] ...
The house cricket is typically gray or brownish in color, growing to 16–21 millimetres (0.63–0.83 in) in length. Males and females look similar, but females will have a brown-black, needle-like ovipositor extending from the center rear, approximately the same length as the cerci, the paired appendages towards the rear-most segment of the cricket.
Adults reach 15–25 millimetres (0.6–1.0 in) and coloration ranges from dark black to dark brown, although some specimens show a slight reddish tint. [8] The black antennae tend to be longer than the body span of the species. The cerci are longer than the head and prothorax, and the wings do not extend past the cerci. [9]
Field crickets are normally 15–25 millimetres (0.6–1.0 in) in size, depending on the species, and can be black, red or brown in color. [2] While both males and females have very similar basic body plans, each has its own distinguishing feature(s).
At one time, many field crickets found in the eastern states of the United States were assumed to be a single species and were referred to as Gryllus assimilis.However, in 1932, the entomologist B. B. Fulton showed that four populations of field cricket in North Carolina, that were morphologically identical and which were all considered to be G. assimilis, produced four different songs.
The tropical house cricket is slightly smaller than its relative the house cricket, growing about 13–18 mm (0.51–0.71 in). These crickets are light yellowish tan and have two thick black bands. One of the bands runs through the bottom of the thorax while the other goes across the upper abdomen.
Gryllus firmus is very similar in appearance to other crickets found in the southeastern United States, the southeastern field cricket (Gryllus rubens) and the Texas field cricket (Gryllus texensis). It has a black head and prothorax, and a brown abdomen. It can be distinguished from these two species by the coloration and venation of the ...
