Introduction
There are 1100 known species of Satyrinae in the neotropical region. About 400
of these are placed in the Euptychiina. Butterflies within this tribe include
the "ringlet" genera Euptychia,
Magneuptychia,
Harjesia,
Cissia,
Caeruleuptychia,
Magneuptychia, Harjesia etc; together with
Oressinoma and the various "wood nymph" genera i.e.
Parataygetis, Posttaygetis
and Taygetis. Most are inhabitants of the forest
understorey and tend to fly close to the ground. They generally avoid sunlight
and prefer to fly at dawn or on cloudy days when light levels and temperatures
are low.
Until
fairly recently almost all of the "ringlets" were placed in the genus
Euptychia,
but revisions by Forster and Lamas divide this
"convenience" genus into a number of smaller genera, on the basis of
anatomical differences and larval foodplants.
The 15
Cissia
species
are smaller than most other members of the Euptychiina. They are generally a
dull plain earthy brown colour on the upperside. On the underside they are pale
brown with broad dark brown bands and a creamy outer band. The hindwings have 2
large black ocelli within each of which is a pair of silvery highlights.
Cissia proba
is known from Ecuador, Peru and Bolivia. It probably also occurs in Rondonia,
Brazil.
Habitats
This species is found in primary rainforest at altitudes between about
200-1000m.
Lifecycle
I have no information specific to proba. The
lifecycle is probably very similar to that of other Cissia
species, all of which produce round eggs with vertical striations. The eggs are
laid either on or near the foodplants, which according to species may be either
grasses ( Poaceae ), palms ( Arecaceae ), or arrowroots ( Marantaceae ). The
larvae unlike those of most other Satyrines only have 4 instars. When fully
grown they are brownish in colour with numerous thin darker and paler lines
along the back and sides. The body tapers noticeably towards the head and tail.
The latter has a pair of short caudal prongs. Like most other Satyrine larvae
they are crepuscular or nocturnal feeders, and hide at the base of plants during
the daytime. The pupa according to species may be pale green, brown or blackish,
mottled or peppered with darker markings. It hangs by the cremaster from a stem
or leaf of the foodplant.
Adult behaviour
As with other Cissia species,
proba is solitary in behaviour. It
flies in cloudy or
sunny conditions, usually deep deep within the forest.
