SOUTH AUSTRALIAN BUTTERFLIES
Signeta flammeata (Butler) (Bright Shield-skipper)
First instar larvae (2mm) newly emerged from egg
Newly constructed tip-folded leaf shelter, typical of first instar stage larvae.
Newly constructed rolled-tube leaf shelter, typical of first instar stage larvae.

Shelter was made on a kikuyu grass leaf.
Second instar larva (4mm)

Typical multi-leaved shelter constructed by larger larvae,
in this example by an early fourth instar larva on kikuyu
Fourth instar larva (10mm)
Final fifth instar larva (25mm) near quiescent
The tiny white dots on the skin are secondary setae
Head of fifth instar larva; of living larva on left,
and of the shed larval skin after pupation on right.
Rolled leaf and bark debris within host grass used as shelters by fourth
to fifth instar larvae.
The shelters are lined with silk and the ends anchored with silk to the grass stems or other debris.
(In this example the shelters are being used by larvae of Dispar compacta, but S. flammeata shelters are similar)
