65 gallon reptarium. I like using these big reptariums for moths. I'll gather the cocoons and place them inside. When a female moth ecloses I'll leave her in the cage and let her call to a mate. When one shows up I'll unzip a corner and fold the flap down so he can find his way in. Zip it back up and wait for nature to have a go at it. Once the mating is over I'll release the male and put in a potted larval host plant for her to lay eggs on.
Of course, moths being moths - they pretty much lay their eggs on anything! More often than not I've had eggs glued onto the mesh. I started pinning slightly crumpled brown paper to the inside walls. It's so much easier to snip the paper with the egg clusters on it and move it into a caterpillar rearing container to continue the cycle.
