Red-tipped Shadefly

The genus name Argiocnemis is derived from -cnemis, from the Greek κνημίς (knēmis, "greave" or "legging"), a suffix commonly used in damselfly names, and a prefix Argio- of uncertain origin, possibly from the Greek ἀργία (argia, "idleness" or "leisure") or formed as an anagram of Agrio-, based on the genus Agrion. The species name rubescens is Latin for "becoming red" or "blushing". Edmond de Sélys Longchamps named this species of damselfly for the colour of the upper surface of its abdomen.
