SOUTH AUSTRALIAN BUTTERFLIES
Signeta flammeata (Butler) (Bright Shield-skipper)
Newly laid eggs are green coloured.
Fertile eggs a couple of days after being laid are still green coloured
but have acquired
an irregular purplish-brown coloured lateral band.
Fertile eggs a week after being laid have lost the green colour and turned yellow.
Larva in fully developed egg on left is in the first stages of cutting
out the top of the egg shell.
Larva in egg on right has completely breached the top of the egg shell, but still
has to double the size of the opening before it can escape from the egg shell.
