Common Silver Xenica
(previously known as : Lasiommata lathoniella)
SATYRINAE, NYMPHALIDAE, PAPILIONOIDEA
The Caterpillar of this species feeds on various grasses ( POACEAE ) such as:
The Caterpillar is green or brown, with pale lines along the body, and a dark dorsal line. The head is about the same colour as the body, and rounded. The anal segment has a forked projection.
The pupa is formed hanging head downward from a cremaster. It is brown with a forked head and spiky protuberances on the body. Its length is about 1 cm.
The adult is dark brown with orange markings and one eyespot on top of each wing, one under each fore wing, and two under each hind wing.
Underneath, each wing has a yellow line accompanied by a row of silvery spots along the margin, and the hind wings have a silvery crescent around each eye spot. The butterflies have a wing span of about 3 cms. The best way to catch them is at dawn when they can be found resting on grass stems covered with dew, and one only has to pick them up.
The eggs are brown and spherical. They are attached singly to leaves of a foodplant.
The species is found as several races in the south-east quarter of Australia :
