The survey carried out in March - December 2021 has revealed the presence of Forty-seven Rhopalocera species under families: Hesperiidae, Lycaenidae, Nymphalidae, Papilionidae and Pieridae, belonging to 37 genera five families from district Srinagar.

While butterfly responses to climate change are well studied, detailed analyses of the seasonal dynamics of range expansion are few. Therefore, the seasonal range expansion of the butterfly Heliconius charithonia L. (Lepidoptera: Nymphalidae) was analyzed using a database of sightings and collection records dating from 1884 to 1992 from Texas. First and last sightings for each year were noted, ...

The biology and the external morphology of the immature stages of Callicore pygas eucale (Fruhstorfer, 1916) (Lepidoptera: Nymphalidae: Biblidinae) are described. Immatures were collected on Allophylus edulis (Radlkofer) (Sapindales: Sapindaceae) in Curitiba, Paraná, Brazil, and reared in the laboratory. Morphological descriptions and illustrations are given based on observations through electr...

In this paper, two methods for assessing the degree of melanization of pupal exuviae from the butterfly Heliconius erato phyllis, Fabricius 1775 (Lepidoptera, Nymphalidae, Heliconiini) are compared. In the first method, which was qualitative, the exuviae were classified by scoring the degree of melanization, whereas in the second method, which was quantitative, the exuviae were classified by op...

The sequence evolution of the nuclear gene wingless was investigated among 34 representatives of three lepidopteran families (Riodinidae, Lycaenidae, and Nymphalidae) and four outgroups, and its utility for inferring phylogenetic relationships among these taxa was assessed. Parsimony analysis yielded a well-resolved topology supporting the monophyly of the Riodinidae and Lycaenidae, respectivel...

Protapanteles (Protapanteles) enephes (Nixon, 1965) (Hymenoptera, Braconidae, Microgastrinae) was reared from the host Fountainea ryphea phidile (Geyer, 1837) (Lepidoptera, Nymphalidae, Charaxinae), collected on Croton floribundus Spreng. (Euphorbiaceae) in São Carlos, São Paulo state, Brazil. The hyperperparasitoids Conura sp. (Hymenoptera, Chalcididae) and a Pteromalidae species are registere...

The exploitation of polarized light may increase perceived visual contrast independent of spectrum and intensity and thus have adaptive value in forest habitats, where illumination varies greatly in brightness and spectral properties. Here we investigate the extent to which Costa Rican butterflies of the family Nymphalidae exhibit polarized wing reflectance and evaluate the types of habitats in...

Some intracellular symbionts of arthropods induce a variety of reproductive alterations in their hosts, and the alterations tend to spread easily within the host populations. A few cases involving the spread of alteration-inducing Wolbachia bacteria in natural populations with time have been reported, but the investigations on the increasing trend in counteracting the bacterial effect on hosts ...
