Well, that explains everything! LOL
I would not trust their info. They tell me all kinds of stuff all the time. Only an hour drive from me and my old stomping grounds, though I never graduated. Couldn't take the nonsense. The Clemson link, not the other.
It must take a lot to get them hungry because I forgot to feed mine for a week (hate the way I changed them to the other side of the room) and just went to check on them. I swear a few sat up and begged when I opened the top! There was no food anywhere in there! I gave them some carrots and broccoli and they went to town!
Maybe it is a different kind of beetle? Isn't there 2 kinds of darkling beetles?
Has to be! It says they are attracted to light in the article. Mine hate light! When I have opened the lid at night and use a flashlight to see inside better they all scurry away from the light. They are fine with noise and me peering in but hate the lights.
