Chalcosoma atlas- The Atlas beetle.
The Atlas beetle is easy to rear but larvae are very viscous. Larvae grow much better if fed high protein diets beyond the normal rotten wood and compost. Larvae will kill and eat each other if given little space or food but if given 2 liters (1/2 gallon) per larvae will live happily together unless really hungry.These larvae also like to bite the hand that feeds them. Minor males ,like the pupa photo on the left, are common if not fed a lot of protein in the first two instars. Raising major male imagos takes extra effort but is well worth it.
