I bought a box of 10 fruit beetle larvae a while ago, and all was going well, all munching, until they suddenly got this crazy mite infestation. I put it on a shelf away from all our other beasties and now it has calmed down, however the substrate dried out a bit and as far as I can see all of them have pupated.
I was lucky enough for one to only make half a cocoon, the other half being the plastic edge of the tub, so I can see inside and see whats going on, which is pretty cool.
Any advice for "hatching" this little chaps out?
