Butterflies of the Amazon and Andes
Gnosia Hairstreak
Gargina gnosia  HEWITSON, 1868
subfamily - THECLINAE
Gargina gnosia, Rio Onolulu, Tingo Maria, Peru Adrian Hoskins
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.
Robbins assigned 9 species to the genus Gargina, i.e. gnosia, gargophia, thyesta, caninius, emessa, humber, thoria, panchaea and another as yet un-named taxon. It is likely that further species will be discovered in the near future.
Males of Gargina are a dark earthy brown on the upperside, with an iridescent blue-violet suffusion on the basal half of the wings. In gnosia this iridescence is confined to the hindwings. Males are also distinguished by the presence of a prominent oval patch of androconial scales toward the end of the discal cell of the forewings. Females are plain earthy brown above.
Gargina gnosia is the most widely distributed member of the genus. It can be found from Mexico to Argentina.
This species is found in rainforest at altitudes between about 200-800m.
To be completed.
Adult behaviour

Both sexes almost certainly spend the major part of their lives in the forest canopy. Males however occasionally descend to imbibe mineralised moisture from the surface of rocks and boulders along the edges of streams.
