Erythrism
From Wikipedia, the free encyclopedia
Contents |
Erythrism or erythrochroism refers to an unusual reddish pigmentation of an animal's fur, hair, skin, feathers, or eggshells.[1]
Causes of erythrism include
- genetic mutations which cause an absence of a normal pigment and/or excessive production of others[2]
- diet, as in bees feeding on maraschino juice[3]
Erythrism in katydids has been occasionally observed. The coloring might be a camouflage that helps some members of the species survive on red plants.[4]
