The "rings" belonging to the genus Ypthima are amongst the most common butterflies in Peninsular Malaysia. However, the species can be difficult to tell apart, with keys relying on minor and often non-discrete ring characters found on the hindwing. Seven species have been reported from Peninsular Malaysia, but this is thought to be an underestimate of diversity. DNA barcodes of 165 individuals,...

—A new species of Tithorea, Tithorea pacifica n. sp., is described and diagnosed from pluvial premontane rain-forest in northwestern Ecuador. Two additional new subspecies, T. pacifica euphonia n. ssp. and T. pacifica concordia n. ssp., are also described, from western Colombia and extreme eastern Panama, respectively. Adult specimens and genitalia of both sexes are illustrated for the three kn...

Three new species and a new subspecies of Calisto Hübner are described from Cuba, Calisto torrei sp. n. Núñez, Calisto dissimulatum sp. n. Núñez, Calisto aquilum sp. n. Núñez, and Calisto aquilum occidentalis ssp. n. Núñez. The immature stages of C. torrei and C. dissimulatum are also described. Notes on the distribution and biology of the species are given.

Adult males and females of many insect species are expected to adjust their daily activity pattern in order to avoid stressful climatic conditions and increase the chances to encounter sexual partners. Using scan sampling methods associated with focal individual observations it was found that two satyrine butterflies of similar size and morphology, Hermeuptychia hermes (Fabricius) (Leptidoptera...

The present study examines the influence of nitrogen on growth rates, morphological and nutritional characteristics of Passiflora suberosa L., and the corresponding consequences for Heliconius erato phyllis (Fabricius) growth and oviposition. The treatments consisted of different nitrogen doses (0, 150 and 300 mg L(-1)) applied to the soil. Newly emerged larvae were individually reared in the l...

A new species of Euptychia Hübner, 1818, from the Amazon basin and the extreme southern edge of the Guianas, E. alacristata sp. nov., is described and compared to its congeners, from which it differs in genitalia, wing shape, and the presence of an androconial hair pencil on the dorsal hindwing.
