Hi everyone. I just started breeding beetles so I still don't know a lot of things. I heard they hibernate. Is that true? And how can I know they're hibernating? I have 2 males Coelosis Bicornis and a female Heterogomphus. Right now, is a bit cold here, and the beetles don't seen to want to get out of the cage. Actually, don't even get out from the soil, they stay there for days. What could that be? Should I be worried or this is normal? They stay under the soil just because it is cold or they're really hibernating?
