Mealworm Madness #4



The Mealworm larvae are rocketing along. They’ve doubled in size again and are easily recognised for what they are even with the naked eye. Mostly, they’re about 1 1/2 centimeters long now and almost ready for feeding to the chooks.

They are papers and very light, so work their way to the top of the bran in which the Mealworms live.With insects, each stage in between molts is called an ‘instar’ and mealworms can have up to 20 molts before maturity.

The trays are getting full of frass. ‘Frass’ is what the powdery leftovers from insect meals is called and when you have this many hungry mouths, it can build up quickly. Much faster, in fact, than I expected.

I’ll do a post on cleaning out the Palace in the next couple of days. That nearly completes ‘Mealworm Madness’ as the life cycle of the Mealworms is nearly complete.
