Cautery-induced colour patterns in Precis coenia (Lepidoptera: Nymphalidae).
Cautery of the dorsal hindwing in the butterfly, Precis coenia, induces the formation of a concentric colour pattern around the site of injury. The induced pattern is identical in pigmentation to the eyespots that normally develop on this wing surface. This response to cautery also occurs, though much less dramatically, on the ventral forewing. In addition to the peculiar response to cautery, t...
متن کاملOmmochrome Pigmentation of the linea and rosa Seasonal Forms of Precis coenia (Lepidoptera: Nymphalidae)
Precis coenia exhibits a seasonal color polyphenism. Animals reared under long-day conditions develop a pale tan pigmentation on their ventral hind wing (the linea form), whereas animals reared under short-day conditions develop a dark reddish-brown pigmentation (the rosa form). This developmental switch is mediated by a shift in the timing of ecdysteroid secretion at the outset of adult develo...
متن کاملHormonal control of GTP cyclohydrolase I gene expression and enzyme activity during color pattern development in wings of Precis coenia.
Color patterns of butterfly wings are composed of single color points represented by each scale. In the case of Precis coenia, at the end of pupal development, different types of pigments are synthesized sequentially in the differently colored scales beginning with white (pterins) followed by red (ommatins) and then black (melanin). In order to explain how formation of these different colors is...
