Some sites mention beetles eating young, some dont. There is so much variation that i dont know what to believe as far as the time cycle, so i once my eggs hatch im going to keep my own records and ill let you know what i find as time cycle from egg to adult. I am picking pupae and beetles out each day (except weekends, since they are at school). Im only planning on cycling my beetles between drawers so hopefully they wont be around the babies.
