Unfortunately although I have a box full of beetles, there do not appear to be any new worms hatching.  The beetles have managed to squeeze through the mesh down into the box where their eggs were supposed to be collecting.  I managed to scoop out enough of the substrate (porage oats) and transfer it to another box where I had hoped that the eggs would hatch into new mealworms, but so far there’s no sign of that.

Meanwhile, the beetles are happily feasting on their own eggs until I can find a smaller mesh to separate them.

Oh, well, try again!
