Kallima albofasciata Moore 1877 (Lepidoptera: Nymphalidae), a species of Oakleaf butterfly reported for the first time from the Andaman Islands in 1874, was recognized as an insular endemic in 1877. Studies so far indicate that it is restricted to the contiguous islands of South and Middle Andamans. On these islands it apparently has a very localized distribution, giving rise to fears that it m...

Selective pressures from host plant chemistry and natural enemies may contribute independently to driving insect herbivores towards narrow diet breadths. We used the specialist caterpillar, Junonia coenia (Nymphalidae), which sequesters defensive compounds, iridoid glycosides, from its host plants to assess the effects of plant chemistry and sequestration on the larval immune response. A series...

Exposure to temperatures above 29?C has been shown to be detrimental to the de velopment of Monarch Butterfly (Danaus plexippus L.) (Lepidoptera: Nymphalidae) larvae, while it has been assumed that temperatures above 33? are lethal. However, the details of larval sensitiv ity to high temperatures are not clearly understood. We examined the effects of different lengths and timing of high-tempera...

A new species, Lymanopoda paisa n. sp., is described from the northern extremity of the Colombian Central Cordillera in Antioquia. It is closely related to L. ionius, as indicated by the male genitalia and underside colour pattern. However, L. paisa has an unusual upperside colour pattern with a large, light blue patch covering basal two-thirds of the wings. It is apparently endemic to the nort...

Anartia fatima and Anartia amathea (Lepidoptera: Nymphalidae) are sister taxa whose ranges abut in a narrow hybrid zone in eastern Panama. At the center of the zone, hybrids are abundant, although deviations from Hardy-Weinberg and linkage disequilibria are strong, due in part to assortative mating. We measured differences across the zone in four wing color-pattern characters, three allozyme lo...

We report a rapid radiation of a group of butterflies within the family Nymphalidae and examine some aspects of popular analytical methods in dealing with rapid radiations. We attempted to infer the phylogeny of butterflies belonging to the subtribe Coenonymphina sensu lato using five genes (4398bp) with Maximum Parsimony, Maximum Likelihood and Bayesian analyses. Initial analyses suggested tha...

The social wasps are predators of many insect species and the study of their preys can reveal the potential of these natural enemies in biological control programs. A total of 240h of collections of preys in 32 nests of Polistes versicolor (Olivier) was carried on in Juiz de Fora, Minas Gerais State, Brazil, from March 2000 to February 2001. The preys captured by P. versicolor were mainly those...

Cyllopsis emilia Chacón and Nishida, a new satyrine species, is described from a single male specimen from Cerro de la Muerte, San José, Costa Rica. This new species can be distinguished from other species of Cyllopsis by its white coloration.

The immature stages of the butterfl y Magneuptychia libye (L.) are described, and their morphology is compared with other Neotropical Satyrinae.
