Species Name: Prodasineura verticalis
A medium-sized damselfly of clear streams, with hindwings measuring 19-20 mm and abdomen about 30 mm. The male is mostly black with bright orange stripes on its thorax and small yellow spots on the abdomen. The pterostigma or wing spot is diamond-shaped and dark brown in colour. The female is similarly coloured but her thoracic stripes are paler and more yellowish. I have seen this species in the streams near the Madai waterfall, Silam and the Tabin Wildlife Reserve all in Lahad Datu.
Males are often seen hovering over fast flowing stream when they are rather difficult to see. Oviposition takes place on vegetation, and submerged roots in shallow running water, with the pair in tandem. (See my second photo.)
The common name (in India) for members of family Protoneuridae is Bambootails and P. verticalis is the Black Bambootail. The distribution range of this species is China, India and most of Southeast Asia.
