Butterflies of the Amazon and Andes
Mountain Greenstreak
Cyanophrys longula  HEWITSON, 1868
subfamily - THECLINAE
Cyanophrys longula male, Medellin, Colombia 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.
There are 17 Cyanophrys species, found variously from Mexico to Paraguay. All have metallic green undersides, marked with a row of white dots on the hindwing. All species possess a filamentous tail, but this is usually lost on examples that have been flying for more than a couple of days.
Cyanophrys longula is distributed from Mexico to Colombia and Venezuela.
This butterfly is found in cloudforest habitats at elevations between about 1400-2400m.
To be completed.
Adult behaviour

Males spend most of their time perching on bushes, where their green colouration affords them excellent camouflage.
