subfamily - THECLINAE
Tribe - EUMAEINI

Almost all neotropical Theclinae species are placed in the Eumaeini.
The tribe is not particularly well represented in collections, so
until fairly recently a high percentage remained unstudied, and were
inappropriately filed away in the 'convenience' genus
Thecla. Many taxonomists have attempted
to rationalise the systematics of the Eumaeini, the most recent
being Robbins who published a revision in 2004, reclassifying the
taxa into 83 genera. Currently there are 1058 known species. Taking
into account their small size, secretive behaviour, and the great
similarities between many species, it is estimated that about
another 200 species probably remain to be discovered.
The genus Calycopis comprises of 72
species, variously distributed from Mexico to Paraguay. The males of
most species have metallic blue uppersides, while the females in
most cases tend to be a dull earthy brown colour. Both sexes of all
Calycopis species and have convex outer
margins to the forewings. The undersides bear a dark post median
line, and usually a short vertical line at the end of the discal
cells. The hindwings have a distinctively shaped wiggly 'hairstreak'
post-median line, and most species have either one or two
black-centred red spots at the tornus. The hindwings also bear 3
short white-tipped tails.
Calycopis calus is one of the few
species in which the underside ground colour is umber rather than
grey. On the upperside males are blackish brown, with the hindwings
and the basal half of the forewings brilliant silvery blue.
This species is distributed across most of tropical South America.
This species is found in rainforest and cloudforest at elevations
between about 200-1600m.
To be completed.
Calycopis butterflies probably spend most
of their lives at or near ground level, and are popularly known as
Groundstreaks. They seem to obtain all their sustenance from moisture
imbibed from the ground, or from the surface of leaves.
