Yesterday, I had a look at my mealworm beetles and they seemed perfectly happy, running around and trying to hide under a piece of wood in their container. When I looked more closely, I realised I could only see 3 of them. I checked through all of the bedding, but there were no dead bodies.
I think 1 of them has either escaped, or been thrown away when I changed their paper towel (I put a damp paper towel in with them for moisture).
Also, I still haven’t found any babies in there, which is odd because I have seen them mating a few times. I think I will have to give in a buy a starter mealworm colony.
