Not kept up with this as I had intended, but there you go!
All but three of the a.pernyi cocoons have emerged, I've had 6 observed pairings and have been distributing eggs to friends in order to avoid a population explosion of caterpillars!
I took 17 cocoons, weighing 20g, and degummed them yesterday. I now have 7.1 g of gorgeous tussah silk that you can see in the picture, together with a gummed cocoon and a moth. The cocoon is to the upper right hand side of the moth.
The Giant Atlas babies are growing well, as are the Emporer and s.ricini, and the Great Peacock babies have hatched at last, though they are doing their best to escape! I've found them all over the place - the lid on their little box must not be a good fit, so they now have a new home, hopefully escape proof.....
