Cup moth fly

Chetogena sp.


About 9 months ago I found a moth cocoon which was slightly unusual in size, colour and location so I decided to grow it out. Today shock, horror and delight when a fly finally opened the lid, climbed out and stretched it's wings.


On a Grevillea stem growing closely entwined with a small eucalyptus tree in a local nature reserve.

All sorts of questions are raised !! Missions?... started as a moth finished as a fly.

The same happened to me last season.
This is why gall identifications are sometimes so hard.

Gob-smacked !! Brilliant as far as spottings go... The other amazing and puzzling bit was all the cup moth cocoons on the neighbouring gum tree were raided but nothing had touched this cocoon - wonder why ??
