General Species Information:
Found on Ellura (in the Murray Mallee, SA), and elsewhere
We see cases from Faggot Case Moths (Clania ignobilis) quite regularly. We finally found a complete one and thought it'd be gr8 to house it in an insect box by the window (to get appropriate light) to finally get images of the adult.
While disapointed that it was parasitised by this fly, we were excited to discover another species.
Rather than injecting eggs into the case, the mother lays eggs on the food plant / leaf that the caterpillar eats. The eggs don't get digested but stay inside the larva until it grows and when about to pupate, use the energy for itself and consumes the moth.
Still baffled at how it managed to get out of the case (it's incredibly strong); one can only assume it saw light at the end of the tunnel and chewed it's way out.
