Sightings of Little Bloodtail, or
Lyriothemis acigastra, a small, colourful and elusive dragonfly whose life cycle is tied to the southwest monsoon, had been widely recorded from the State.
Large numbers of the dragonfly are known to emerge from aquatic larval stage with the first rains of June. They disappear as the southwest monsoon wanes by September.

A four-month dragonfly survey that concluded at the Wayanad Wildlife Sanctuary (WWS) recently spotted 84 species of odonates (order of insects comprising dragonflies and damselflies) belonging to 59 genera under 11 families.
The survey was jointly conducted by the Forest Department and Ferns Nature Conservation Society (FNCS). Of the 84 species, 49 were dragonflies and 35 damselflies. Muneer Tholpetty, secretary, FNCS, told
The Hindu.
A previous survey by the Malabar Natural History Society (MNHS) in the sanctuary in 2016 had identified 75 species of odonates belonging to 50 genera under 11 families.
“Since odonates are amphibiotic insects, the study focused on waterbodies in the sanctuary. Ponds were the richest in terms of species, but streams had the most number of endemic species,” Mr. Muneer, who coordinated the survey, said.
