Distribution and habitat characteristics of the Troidinebutterfly community in the Western Ghats, a biodiversityhotspot in India Anto, Mary; Mathew, George; Jose, Roby T. Investigation on the distribution patterns and habitat requirements of the butterflytribe, Troidini was carried out in undisturbed forest habitats and disturbed, human-modiûed habitatsin the Western Ghats, a biodiversity hotspot in south India. Compared various ecological andbiological traits of the four species of this group which included a CITES (Convention on InternationalTrade in Endangered Species of Wild Fauna and Flora) listed species, Troides minos Cramer, anendemic species Pachliopta pandiyana Moore, a protected species, Pachliopta hector Fabriciusand Pachilopta aristolochiae Linnaeus. Comparisons were based on transect counts conducted at66 transects in 22 locations covering six types of habitat systems with a gradient of disturbance andmanagement regimes during 2009 and 2010. Results indicated that P. aristolochiae was the mostwidely distributed species occurring in 90% of the transects sampled and P. pandiyana had a restricteddistribution (36 %), while both P. hector and T. minos were observed in 73% of the transects. Samplingof the juveniles on the six species of host plants in the various habitats provided insights into hostplant partitioning between these species in the different habitats. Life history traits and morphologicalcharacteristics of adult troidines, larval host plant characteristics and habitat characteristics wereevaluated and characterized. © 2019 Association for Advancement of Entomology

Wing shape differences along a migration route of the long-distance migrant Globe Skimmer Dragonfly Pantala flavescens Johansson, Frank; Hedström, Tobias Kollberg; Anderson, R. Charles; Divakaran, Prathapan K.; Kakkassery, Francy K. Animals which migrate by flying should be subject to selection for optimal wing characteristics that maximize energy efficiency during migration. We investigated wing shape and wing area variation in the Globe Skimmer Dragonfly Pantala flavescens, which has the longest known migration of any insect. Wing shape and wing area differences between individuals in southern Peninsular India, and migrating individuals at a stop-over site on the Maldives, were compared. Results suggest that individuals which successfully reached the Maldives, on their way from India to Africa, had a broader wing base and an overall more slender wing shape than individuals in southern India. Contrary to our expectations, wing area did not differ significantly in most of our comparisons between southern India and the Maldives, suggesting that wing shape is more important than wing area for successful migration in P. flavescens. The results provide indirect evidence of natural selection on wing shape in a migrating dragonfly.

Taxonomical studies of dragonfly nymphs (Odonata, Libellulidae) using their exuviae Adambukulam, Shaun Paul; Kakkassery, Francy K. Taxonomic studies of dragonfly nymphs were done up to species level using their exuviae.Exuviae, being the last instar larval skin, possess all larval features. These features can be used for theidentification of odonate nymphs up to species level. Seven species belonging to the family Libellulidaewere identified using the features present on exuviae. This is a non-invasive method that can be used forthe taxonomic studies of dragonfly nymphs without rearing them in the laboratory. The study describesthe morphological features of seven species of dragonfly nymphs belonging to family Libellulidae usingexuviae. A taxonomic key for the identified exuviae were also provided. © 2023 Association for Advancement of Entomology

A check list of blow fly fauna (Diptera, Calliphoridae) of Kerala including forensically significant species Reject Paul, M.P.; Binoy, C.F. : Seventeen species of blow fly belonging to four subfamilies and eight genera were recorded from Kerala based on field studies and literature. Out of the 17 species, seven are forensically significant, six are pollinators and two species each are carrion breeders and termite predators respectively. The distinguishing features and distribution of all the species are discussed. © 2023 Association for Advancement of Entomology
