Pink Katydid

Pink Katydid ~ The pink colouring of some katydids is due to a condition called erythrism, an unusual reddish pigmentation that can affect an animal's body, skin, feathers, hair or eggshells. It is caused by diet or a genetic mutation that either leads to the absence of a normal pigment or the excessive production of another. In katydids, the pink colouring might be a kind of camouflage that hides them on reddish or pinkish plants.







The pink coloration of the katydids is the result of a condition called erythrism, an unusual reddish pigmentation, and is similar to albinism where the condition is due to recessive genes.
