Mycalesis is one of
the largest Satyrine genera, containing 88 known species, of which 2
have yet to be given scientific names. The genus is confined to the
Oriental and Australian regions.
The butterflies are
instantly recognisable as a group, all being some shade of brown on
both wing surfaces, and marked with a series of conspicuous ocelli,
and a single straight median line across the underside of both
wings. Many of the species are very similar, but can usually be
distinguished from each other by close examination of the
configuration of the ocelli and submarginal lines.
Mycalesis terminus is found in Irian
Jaya, Papua New Guinea and surrounding islands. It also occurs in
Australia ( Cape York ).
inhabits forest glades and open woodland where dappled sunlight
filters down to the forest floor.
The eggs are yellow and globular. They are laid
in clusters of up to 6 on the underside of leaves of the grasses
Oplismenus ( Poaceae ). The fully grown caterpillar is pale
brown with a faint dark dorsal line. It feeds nocturnally and rests
during daytime at the base of a grass tussock. The chrysalis is green
with a dark dorsal line. It is suspended by the cremaster from a grass
blade or nearby stem.
adults are usually seen resting on low foliage in semi-shaded areas in
forest glades or similar semi-open habitats. They never outspread
their wings when at rest, but sometimes momentarily flick them open,
displaying the diematic ocelli on the upperside as a bluff warning to
