Many members of Gomphidae are not easily spotted and most of them are inhibitants of forests. It was my first time to bump into
Onychogomphus castor. I spotted a male and a female
O. castor at the Kijang Waterfall of Kenaboi Forest Reserve. The male
O. castor has a beautiful curved tail (anal appendages).
