Bringing Shadowdragons to light: Neurocordulia (Anisoptera: Corduliidae) systematics

Neurocordulia, commonly called shadowdragons, are crepuscular dragonflies, flying mainly at dusk. The genus comprises seven species, which occur across the eastern part of Canada and the United States. Here, we used targeted enrichment probes to sequence ~1000 loci for all specimens of each species, allowing for the first phylogenetic assessment of the genus.

The larva of Hetaerina duplex Selys, 1853 (Odonata: Calopterygidae) with a key to known Colombian larvae species

The larva of Hetaerina duplex is described and illustrated for the first time based on specimens from Quindío and Risaralda departments of Colombia.

Slow motion analysis of flight curves in Odonata

Slow-motion recordings were used to analyze the flight of different species of dragonflies in the field. The flapping frequencies during the turns increased. The measures leading to curves correspond in the two groups of Odonata, Anisoptera and Zygoptera.

The current state of odonatology in India

In the past 50 years, odonatology has advanced on a global scale in phylogenetics, diversity, organismal and population ecology, and conservation biology. This study explored if such knowledge gains are perceived to have occurred in India, as they did worldwide, and identified knowledge gaps and challenges that might be hindering progress in Indian odonatology.
