I have used them many times in the past as food items for various herps including chams. Chams love them! I have mainly used adults that I have found while herping on a local road near my home. There are times when I can find as many as 20 a night (though I have never captured that many at a time). I normally just grab a few here and there to give my chams or other lizards a treat. My only concern when dealing with wild insects is if they have been in contact with pesticides or not.
Take care,
Brad
