Ribbed Case Moth

Hyalarcta nigrescens


Larval case - What comes out of this cocoon??? This fly-like moth emerged.


Sometimes common on gum trees. They eat leaves over-night, then stitch themselves onto a branch for their daily nap. Neat.


Female casemoths live out their lives inside the case. Males will emerge from one end as tiny clear winged moths.

Yes but if the cocoon is a female they get nothing at all.

Ha! And they get something that looks a lot like a blow-fly.

People sometimes collect this cocoon to await, in hope and futility for the beautiful butterfly to emerge

I haven't seen these since the early 60's... ! Nice to know they're still around.
