Summary
[edit]DescriptionRiver Heliodor, Libellago lineata, young male at Mechode Padur 2.JPG |
English: Libellago lineata, River Heliodor, Stream Heliodor, Yellow-lined Gems, is a small black and yellow damselfly with black tipped transparent wing; confined to hill streams and rivers of forested landscapes. Frequently sits in emergent water plants and overhanging bushes. Their preferred home is along the banks of rivers.
The fully adult male has black and yellow markings along the thorax and abdomen. It has more black when fully matured. It also has white markings on the legs. The biggest difference though, is that it develops black marks on the tops of the wings, that make it look really distinctive. A young male is similar to the adult, but doesn't yet have the black markings on the wings and there is less black on the abdomen. The female is similar to the sub-adult male, except the abdomen is much more robust. and the markings on the abdomen are slightly different. Note: This is Libellago indica Fraser, 1928; now considered as a separate species. Sex male |
