Was just thinking of something. When I was a kid growing up in the midwest I sometimes found something unusual. I would find carolina mantid nymphs (L3 or L4) that would have a very extended abdomen. I later found out that it was caused by a large "maggot" looking parasite living inside the mantis. These mantids never seemed to reach adulthood probably due to the parasite using up much of the mantids food. Funny thing is, I have never seen that since. At least not around here.
