Mycalesis is one of
the largest Satyrine genera, comprising of 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 New Britain. It undoubtedly also occurs
on many of the smaller islands surrounding New Guinea.
inhabits forest glades and open woodland where dappled sunlight
filters down to the forest floor.
I have no data regarding
phidon. The lifecycle of most Mycalesis
species adheres to the following pattern:
The eggs are yellow and spherical. They are laid in clusters of up to
6 on the underside of grass blades, most commonly on
Themeda ( Poaceae ). The fully grown caterpillar is typically
brown with a faint dark dorsal line. It feeds nocturnally and rests by
day at the base of a grass tussock. The chrysalis 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
