Long Frontal Projections Help Battus philenor (Lepidoptera: Papilionidae) Larvae Find Host Plants
Animals sometimes develop conspicuous projections on or near their heads as, e.g., weaponry, burrowing or digging tools, and probes to search for resources. The frontal projections that insects generally use to locate and assess resources are segmented appendages, including antennae, maxillary palps, and labial palps. There is no evidence to date that arthropods, including insects, use projecti...
متن کاملWarning Color Changes in Response to Food Deprivation in the Pipevine Swallowtail Butterfly, Battus philenor
Predation on distasteful animals should favor warning coloration that is relatively conspicuous and phenotypically invariable. However, even among similarly colored individuals there can be variation in their warning signals. In butterflies, individual differences in larval feeding history could cause this variation. The warning signal of the pipevine swallowtail butterfly, Battus philenor L. (...
متن کاملLarger clutches of chemically defended butterflies reduce egg mortality: evidence from Battus philenor
1. Many toxic butterflies lay eggs in clusters and their eggs are aposematically coloured to warn predators. The pipevine swallowtail, Battus philenor (L.) (Papilionidae), is a specialist herbivore on plants in the genus Aristolochia , from which it sequesters toxic alkaloids (aristolochic acids, AAs). Eggs of this group of butterflies are laid singly or in clusters of different sizes, are apos...
متن کاملContemporary patterns in a historical context: phylogeographic history of the pipevine swallowtail, Battus philenor (Papilionidae).
We examined mitochondrial DNA (mtDNA) variation in pipevine swallowtail butterflies (Battus philenor) from throughout its extant range to provide a historical, phylogeographical context for ecological studies of the disjunct population in California. We evaluate current hypotheses regarding host plant use, behavior, and mimetic relationships of B. philenor populations and generate alternative h...
متن کاملWhy have multiple cortical areas?
Image processing requires free access to information about all parts of an image, but a nerve cell in V1 can only interact directly with a tiny fraction of the other cells in V1. The problem this poses might be alleviated by forming secondary "neural images" in which information is re-arranged, and some possible rules of projection for forming such images are explored. It is also suggested that...
