on the contrary, i feed tons of moth species, and actually just spent hours catching and feeding my chams flies moths and other fun treats. Just use your common sense and use a little logic, no pesticides, no gross food sources for the bugs.
do some research. You will find alot of varying answers on the topic. it depends on where you are and your situation. Personally, if it were not for wild caught bugs, i wouldnt have been able to feed my chams some days. I know i'll get all sorts of flax for this but i believe if you use your head and are safe, then there can be benefits.
Oh, Ps. this should be under food! haha
