Theclopsis lydus, Satipo, Peru © Adrian Hoskins
Introduction
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 Theclopsis comprises of 10 known species, variously distributed from Mexico to Peru.
Theclopsis lydus is rarely seen as it spends most of its life in the tree tops, but it is one of the most common and widespread Theclines in the neotropical region. Its range includes Surinam, Guyana, Venezuela, Brazil, Ecuador and Peru.
Habitats
This species is found in primary rainforest habitats at altitudes between about 200-1000m.
Lifecycle
Unknown.
Adult behaviour

Both sexes spend most of their lives in the upper canopy, but males sometimes descend to settle on bushes or saplings in light gaps.
