the Long-tailed Skippers
Urbanus,
Chioides
and
Aguna;
and such familiar genera as
Phocides,
Autochton,
Astraptes
and
Calaenorrhinus.
The
genus Astraptes, comprises of 29 large species characterised by having chocolate brown wings
with very short stubby tails on the hindwings. Most species have a diagonal
hyaline stripe across the forewings and a group of 3 small hyaline spots near
the apex. In the majority of species the head, thorax, abdomen and wing bases
are covered with long fur-like gleaming metallic blue ( or in the case of talus,
green ) scales.
Astraptes anaphus however lacks hyaline markings
and also lacks the greenish or bluish iridescence of its cogeners.
Astraptes anaphus
is a widely distributed species found on the larger islands of the Caribbean,
and on the mainland from Costa Rica to Peru and Bolivia. There are 5 named
subspecies. The Peruvian subspecies illustrated on this page is
Astraptes anaphus aniza

Adult behaviour
The
butterflies have a very rapid whirring flight, often circling
widely at a height of about 2 metres. They commonly settle on
living foliage or dead leaf litter to feed at bird droppings. When feeding they exude droplets of water from their
abdomens, dropping or squirting it onto the bird droppings to
dissolve and liquefy them, enabling the juices to be sucked up
using the long proboscis, which is extended under the abdomen.
