Resting red

Dragonflies could be seen in large numbers at the beginning of October, just after the rains. I’ve been meaning to start identifying them, so when I spotted this in Bhandup pumping station, I took photos from two different angles. It was good that I did that, because I found that the colours of the body, wing, and eyes are needed to complete an identification.

Scarlet skimmers (Crocothemis servilia, aka ruddy marsh skimmers) are common across Asia and are found, as its name suggests, in wet lands. Dredging many websites I found the perfect tool: Subramaniam’s field guide published by the Indian Academy of Sciences. This was a perfect fit: blood red face and eyes, shading to purple at the sides, blood red thorax, reddish hue on the legs. The colour of the thorax told me this was a male; females are paler, and shade towards an yellow. In confirmation of the ID, the wings were transparent, with an amber-red base, and the wing-spot was brown.

I’m glad I made a start; reading descriptions in a field guide also tell you what to look for in future. I should have taken a shot from above, to see more clearly the dark stripe which ran along its back. That identifies it as belonging to the subspecies C. servilia servilia. Its lack would have told me that the dragonfly belonged to a different subspecies, identified only forty years ago.

I travel on work. When that gets too tiring then I relax by travelling for holidays. The holidays are pretty hectic, so I need to unwind by getting back home. But that means work.

      1. Same here. I know only a small set of obvious plants, trees and shrubs and to top it, of late, I have started forgetting my taxonomy due to lack of practice. But the cryptogams have somehow fascinated me more than the flowering world since my Botany lectures in college, and now that I see my son’s college notes, I find the love rekindling.
