♀44mm 2007-11-25 DRAGONFLY POND More on EGGS OF DRAGONFLIES
|
Urothemis signata insignata. Easily distinguished from other medium-sized red dragonflies by very open venation, pointed wings and brown patch at hw base; veins largely red and distal antenodal complete (see Crocothemis/Rhodothemis)
Female is brown with basal hw patch paler. Lakes, ponds and slow streams in open country and swamp forest margins; fairly common in lowlands.
Male rest in bright sunlight, commonly adopting the
'obelisk' position with abdomen held upright. Widespread in Indo-Australian
tropics.
Urothemis signata insignata is a medium-sized red species (hw, 35-37 mm). Unlike other
species of similar size and color, the reticulation is very open and the major
veins are bright red. It can also be distinguished by the small, solid
reddish-brown patch at the base of the wings instead of a hyaline yellow area.
It is most commonly found on the sunny borders of drains and lakes in the
lowlands but ranges up to 600 m. Males fly little and frequently rest for long
periods in the sunlight in the 'obelisk' position, in which the wings are
depressed or canted away from the sunlight and the abdomen is held vertically, a
behavior believed to prevent overheating.
