You are quite right! And theoretically they could even become invasive species here in the great white north because they can overwinter as eggs. The adults may not survive the winter but the eggs most certainly will.
Thanks for the info. I bet a lot of people on this forum would be appalled at feeding chams something like an E. Tiaratum. I personally never remove grasshoppers spiny legs because the chams can't get too pampered...:D
Get some stick insects. They are extremely prolific and breed parthenogenically (absence of a male) Chameleons also love them. In the wild a chameleon would eat a lot more stick insects and mantids than crix. You should also add other insects for variety but sticks are a good start. Search...
Do what I do...
Come spring catch about 50 adult grasshoppers/katydids/whatever you want to feed
Set up a breeding program
You can find info on how to breed crickets, locusts, grasshoppers, and katydids on the internet.
Feed of the first generation captive baby bugs.
