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 کاملThe phylogenetic pattern of speciation and wing pattern change in neotropical Ithomia butterflies (Lepidoptera: nymphalidae).
Species level phylogenetic hypotheses can be used to explore patterns of divergence and speciation. In the tropics, speciation is commonly attributed to either vicariance, perhaps within climate-induced forest refugia, or ecological speciation caused by niche adaptation. Mimetic butterflies have been used to identify forest refugia as well as in studies of ecological speciation, so they are ide...
متن کاملColour pattern modification by coldshock in Lepidoptera.
When young pupae of Vanessa cardui, V. virginiensis and Precis coenia (Lepidoptera: Nymphalidae) are exposed to severe coldshock many develop aberrant adult wing patterns. For each species, a synchronous cohort of experimental animals always develops a broad range of aberrant pattern morphologies but these can always be arranged in a single unbranched morphological series. When such phenotypic ...
متن کاملPhylogeny of the Nymphalidae (Lepidoptera).
A generic-level phylogeny for the butterfly family Nymphalidae was produced by cladistic analysis of 234 characters from all life stages. The 95 species in the matrix (selected from the 213 studied) represent all important recognized lineages within this family. The analysis showed the taxa grouping into six main lineages. The basal branch is the Libytheinae, with the Danainae and Ithomiinae on...
