if you release them,then something bad will happen.....
THIS DOES NOT MEAN YOU CANT BREED THE MOTHS YOU WANT!
just breed them in captivity,releasing a male and female together.if you see them around,or come across eggs/larvae,then start releasing a few pairs at a time.as someone else said, try improving habitats, for example, if you have room,plant a tree for eyed hawks,sallow or apple,for garden tigers,let some weeds(weeds equal= nettles, dandelion, dock,etc.) grow in a patch that suits and plant nectar rich plants for all kinds of nature!(again, only if that suits.)
Hope i helped! And good luck!
PS.Never let yourself down!!!!!!
