The Lucky Reptile Fly Feeder is a great feeding tool for flying insects such as fruit flies, curly wing flies, soldier flies, bluebottles, waxworms etc. The pupae or fly culture can be set up in the container and when they begin to emerge, the Fly Feeder can be placed in the terrarium with the bung removed to allow the slow escape of the flying insects. Many species of fly can be cultured in the container so that a continual supply of food can be produced within the enclosure.
