Arashimaru Posted June 2, 2022 Share Posted June 2, 2022 Hello, I have a small colony of Gromphadorhina oblongonota, and since I have a similar amount of males and females, I thought I should cull some of the males so their fighting doesn't stress the colony too much. I would like to feed off the smaller adult males to select for larger individuals, but how can I tell the difference between a small adult and a large nymph?
