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 8 Rekoa species, all of which
are neotropical in distribution. Five of them -
and bourkei are 'typical' hairstreaks -
their undersides are plain brown, marked with red tornal spots on
the hindwings, and the hairline streak from which the popular name
"hairstreak" is derived.
Another species meton has striking
tiger-stripes, and a 'cat's eye' mark on the hindwing. The remaining
two - palegon and
malina, have a series of suffused dark
lines on the undersides. Males of all Rekoa
species have iridescent blue uppersides. Females are brown with only
a vague pale blue sheen.
Rekoa palegon is distributed from
Mexico to northern Argentina.
This species is found in tropical and subtropical forest-edge
habitats at altitudes from 200-800m.
To be completed.
butterflies are normally seen singly. Both sexes nectar at Senecio,
Eupatorium, Lantana and other flowers.
