I get crickets and locusts from the garden in my house.. my understanding is green is a cricket and brown is a locust.. i feed both to my aros.. but there are definitely exceptions.. i've tried prob a couple of times these rather large locusts and they have these serrated legs.. that is a pain.. best would be to snap those off and feed em.. my aros have spat these type of locusts while the legs where still on.. so take care..
