Mealworm beetles (darkling beetles) are prolific breeders. Mating is a three footfall process: 1) The male gives chase until the female relents. 2) The male then mounts the female and curls his genitals (aedagus) underneath himself and inserts it into her genital tract. 3) The male then injects a packet of semen into the female. Dependent on incubation temperature, just days after mating the female will burrow into soft ground and lays about 500 eggs.
Creatures that are the Mealworms most familiar choices for live foods, ranging from feeder mice to crickets and mealworms, generally are noble and raised in captivity themselves, and can often be found both through local pet stores and from wholesalers or "farms" that breed them specifically for live food sales.
