I am very sorry when you lose a mantis
as you are definately an excellent caregiver for them :wink: . I find it great that you do the specimen thing (my youngest collects all of our specimens including molts) - I actually did a lot of birds and a few mammals in my younger years and still have an old coot (really! and it is not me or my husband!) in the basement that I bring to schools for teaching. ANYHOW, I was just going to let you know at university and home we always used cheese cloth for wrapping. Maybe that would help with the shipping. It is very inexpensive and then you can use insect pins to pin the cheese cloth to styrofoam and then cover it with the cup and send it. You can wrap a few layers around for security and stability. My coot has about 10 wraps to keep it from getting dust & moisture etc. It was collected in about 1990 and is in mint condition. Is it possible, I wonder, to relax them afterwards in posed positions? Now that would sure be neat for teaching! Good luck! H.
