These tiny larvae (approx 2mm long each) have just hatched from long, rounded cream coloured eggs and have eaten the empty shells. They are now gathering around wondering what to eat next.
Eucalyptus leaf on large E.microcarpa in wetland reserve.
Exact species unknown although several adult P variicollis were also found on the tree. I just thought they looked cute hanging around. They would have just hatched form eggs then eaten the shells.
