Tim Taylor writes on August 13: "On April 28th 2013 in Campbell River BC my buddy Wyatt collected a fresh female Hyalophora euryalus. Since I was on my way there I got him to put it in a brown paper bag for me. Over the next week she laid about a 100 eggs. On May 9th they started to hatch, and there was still four feet of snow on the ground back in Saskatchewan!

"Since the local trees were no where close to bud, off to the the local garden center I went. When I got there they were in the process of unloading a semi full of trees. The first one I spotted was a Siberian Larch (Larix sibirica) with nice fresh needles, so I bought it. It was still to cold outside so I put it in my dinning room that has lots of natural light.

"The little cats loved it and grew very rapidly. By June 1st 90% had reached the fifth instar, everything was going great and then....... I noticed a black spot developing one the tail segment of one cat, I quickly removed it, but it was too late, it had spread to all but one. Even thought I was only left with one cocoon a defoliated Larix and a vacuum full of frass, it was a lot of fun, I really enjoyed watching them develop."
