Color Variation as an Unconventional Defense Mechanism

Antheraea jana shows a plethora of color forms. The genetic and evolutionary mechanisms underlying such variation haven’t been determined yet.​

Saturniidae present different defense mechanisms against predators, as the presence of tails in the forewings (Actias sp., Argema sp. and others) or vivid eyespots (Ex. Automeris sp., Antherina suraka). It is possible to speculate that such color variation might be linked to a less conventional defense mechanisms.
