Orthetrum glaucum ^[2] is an Asian dragonfly species, common across much of tropical and subtropical Asia. The common name for this species is blue marsh hawk. ^{[1] [3] [4] [5] [6]}

Description and habitat

It is a medium sized dragonfly with dark face and greenish blue eyes. The thorax of old males are dark blue due to pruinescence. Its wings are transparent with dark amber-yellow tint in the extreme base. Its abdomen is pruinosed with blue color up to segment 8; last two segments are black. The abdomens of females and juvenile males are golden in color, with brown stripes along the sides of the thorax. ^[7] Despite their visual similarities, females and juvenile males can be distinguished by the shape of their final abdomen segment.

It breeds in marshes associated with forest streams, plantations and canals. ^{[8] [9]}
