Genetic switch in UV response of mimicry-related pale-yellow colors in Batesian mimic butterfly, .

In a Batesian mimic butterfly , mimetic females resemble an unpalatable model, , but exhibit a different color pattern from nonmimetic females and males. In particular, the pale-yellow region on hind wings, which correspondingly sends important putative signals for mimicry and mate preference, is different in shape and chemical features between nonmimetic and mimetic morphs. Recently, we found that mimetic-type [] causes mimetic traits; however, the control of dimorphic pale-yellow colors remains unclear.
