Ooth temp to delay hatching

[alephhat]

As a general rule, would putting oothecae in the freezer prevent hatching without destroying the content? I currently do not have them in the freezer- just asking in advance. I'm not sure what temp would be required to cause the ooth to not hatch until I'm ready for them to do so (I would be hatching them in "waves" as I have a small collection). I just do not want to harm them in the process if possible.

Do you know what species...? Also, do you know how old it is...?

Never, never, never NEVER put an ooth in the freezer! I would never put a tropical ooth in the refrigerator, myself. Has anyone tried this?

I've put all my local ooths when i lived in Michigan in the refridgerator's vegetable drawer to over-winter. I did this with many silkmoth cocoons as well. Some need this to trigger diapuase. So, my guess is whatever he's finding locally in New York will also overwinter their ooths, so fridge or garage with regular misting would be my direction. Or pinned to a tree branch to let nature have her way.

What species were you doing this for, Sporeworld? The only species that i know of in the US that needs diapause is the european mantis, m. oratorio. And remember, contrary to popular belief, cold breaks diapause, it doesn't trigger it!
