v
they will do that because they dont like light...when they turn black they will mate...also once you have hundred plus they will be on top of the bedding...so give it some time..during the day most of them will be under the bedding and towards night time most should be out....I just had my first pupae turn to darkling beetles, and right now there are three beetles. The beetles seem very inactive right now, i havn't seen them eat and it seems like they mostly just burrow down and hide all day. Is this normal for the first few days of the adult stage?
Thanks, any and all answers are appreciated =)
