Bird Grasshopper (nymph)

Description:

From Wiki: The adult male of the species is up to 4.5 centimeters long, and the adult female may reach 5.5 centimeters. The body of the adult is generally yellow-brown in color and the wings are pale with large brown spots. The nymphs are different in appearance.[2] They change color as they mature and their coloration is a polyphenic trait: one that is influenced by environmental conditions, producing multiple forms from one genotype. This is not uncommon among grasshoppers. In this species, the coloration of the nymphs is especially influenced by temperature. Nymphs are various shades of green, yellow, or red, usually with a pattern of black markings. They are often red at lower temperatures, but at higher temperatures, only green and yellow shades occur. Black patterning is also influenced by temperature, with lower temperatures inducing darker markings. Density is also a common factor in color polyphenism, but it is less important in this species than in many other grasshoppers. Nymphs reared in crowded conditions develop darker black markings, but density has little effect on their background colors.
