Family - HESPERIIDAE
subfamily - PYRGINAE
subfamily Pyrginae are characterised by their habit of basking with
wings outspread, compared to the half-open position favoured by the
Hesperiinae. In North and South America 580 species are placed
within the tribe Pyrgini.
There are only 3 Systasea
species - microsticta from Mexico,
pulverulenta which is distributed from
Texas to Guatemala, and zampa.
is found in California, Texas, Arizona and Mexico.
This species occurs
in hot sun-baked habitats, favouring canyons and gorges.
The egg is white and is laid singly on the underside of a leaf of
Abutilon ( Malvaceae ), although up to
6 may be laid on the same leaf by a single female on repeat visits.
The newly hatched caterpillar is translucent green, darker in the
middle and fading to pale straw towards the head and tail, and has a
shiny black head. It constructs a refuge by making a long incision
stretching from half-way along the edge of a leaf to the midrib. It
then pulls over a flap of the leaf, fastening it with silk to make a
distinctive shelter. After each moult the larva builds a new
shelter. Pupation takes place in the final leaf shelter. The pupa is
white and slightly waxy in appearance.
The butterfly is usually
encountered singly. It usually keeps its wings fully outspread while
feeding or when settled for short periods, but holds the wings erect
when at roost.
