There are 19 Oxytenis species, all of
which are neotropical in distribution. The adults have falcate
forewings which in several species including
nubila, sobrina and
mirabilis are deeply excavated. In most
species the hindwings are smoothly rounded but in
zerbina they are strongly lobed. All species have a brownish
ground colour, and are marked with a dark line extending from the
apex of the forewing to midway along the inner margin of the
Oxytenis nubila is found from Costa
Rica to Peru.
This species is found in rainforest and cloudforest at elevations
between about 200-1500m.
The larva when fully grown is green, with a black
patch near the tail. If molested the larva rears up and puffs out
the thoracic segments, exposing a pair of prominent black eyespots,
each ringed with orange and yellow. The general appearance is of a
small tree snake.
adults rest during the day among leaf litter in the undergrowth, or
hanging from stems or small branches.
