236: Ictinogomphus acutus Laidlaw, 1914

           Number: 236 / Family: Gomphidae / Genus: Ictinogomphus
Species: Ictinogomphus acutus Rusty Clubtail*
Province(s) sighted: Narathiwat
Habitat: Peat Swamp Forest
In flight: August / Sightings (by me): Rare
Species easily confused with: N/A

*As there is currently no common name, I have based the name on the genus being known as 'Clubtails' and the appendages of the species having a unique 'rusty' colour. 

Like many species at Sirindhorn Peat Swamp Forest, Ictinogomphus acutus eluded us 'til the last. My brother saw this species a year or so earlier and managed to get a decent shot of it, which we quickly named it the Rusty Clubtail, due to its abdomen end segments. When we arrived, it was nowhere to be seen... except it was! Paul's missus, Suu, saw it perching in the trees and took some nice photos which I will add when I get them processed. Paul even sent images of where it was! Bur the dragonfly guys (me and Noppadon Makbun) missed it again. 2-0 to the birders! As we searched for it, the birders returned and explained where it was... we could see it. The guys wandered off looking for birds. Suddenly, there it was... massive... it WAS still in that tree but it shot off and we watched it disappear over the over side of the lake. It returned shortly afterwards, circled the lake and then, instead of landing in the same tree, it decided it had had enough and lofted off high and far into the distance. It was a beautiful, of not fleeting, glimpse of it, but enough to count it for my records. Until I return, I am using Paul's shot of it from his previous trip.

The Male
The male is very easy to recognise and is found in Mainland Malaysia just over the border so it isn't a surprise to find it here. Check out the 'rusty' end of its abdomen... definitely a beast of a dragonfly and hope to get my own photos next trip!
