Family Platycnemididae
Genus Copera

we have in our image records two species in this Genus Copera:

1 Copera marginipes

2 Copera vittata

Copera are creatures of the plains below 500 meters found on sluggish streams and in swamp forest. They sometimes venture into the open at forest margins. The larvae are quite distinctive, with a fringe of long, fine filaments around the margins of the caudal lamellae. They are found among detritus and root masses in the banks of slow flowing steams.

Two recognized species occur in Borneo. Copera vittata and Copera marginipes
 


Copera marginipes

They are found in similar situations with Copera vittata  but mainly in the South Borneo where both species may fly together. It is easy to recognize the males by their expanded, bright yellow legs.


Copera marginipes is similar to Copera vittata  in build; synthorax marked with yellow streaks; legs flattened and yellow; 'ghost' forms occur among immatures. Habitat similar to last, including clear streams. Widespread in tropical Asia.

 


Copera vittata

is common everywhere in swampy forested places, even in very disturbed habitat so long as it is shaded. Typically, Copera vittata has red legs but a common form found in Brunei by A.G. Orr has black legs.


Immature individuals appear in pale whitish 'ghost' forms.
 

Copera vittata is slender and dainty; variegated pattern of greenish yellow maculation on synthorax; legs orange red. Variants may represent separate spp. Immatures mainly pale ivory, known as 'ghost' forms.
Found in sluggish channels and shallow pools in swampy forest. Widespread in tropical Asia.
