Field grasshopper

Description

horthippus brunneus, also known as the common field grasshopper, is a species of grasshopper of the subfamily Gomphocerinae.It was first described by Thunberg in 1815. It is also known as Gryllus brunneus, although this name has not been adopted by the IUCN.The IUCN lists C. brunneus as Least Concern. C. brunneus are predominantly brown. However, they show a large variation in colour and can also be black, green, purple, or white. Wing patterns vary between individuals and can be mottled, striped, striped-mottled, or plain. Both green and purple grasshoppers tend to have plain forewing patterns while black grasshoppers primarily have mottled forewing patterns. Brown grasshoppers do not consistently have the same forewing pattern instead they have variable forewing patterns. At least two loci are responsible for pronotum color in C. brunneus.Green alleles are dominant to all other colors while brown alleles are recessive to all other colors. Wing pattern is determined by a separate locus than colour.The plain forewing pattern is dominant and the striped and mottled forewing patterns are codominant.
