Here is the tiny first instar caterpillar.  Like many youngsters, it was exceedingly active and it wouldn’t stay still for a decent photograph.

   As soon as I saw that the egg had hatched I went up to Mount Tolmie to get a fresh Mahonia leaf for the young caterpillar to feed upon.  With a pair of scissors I snipped off the first decent-looking fresh leaf that I saw, and I hurried home.  Only when I looked at the underside of this leaf did I see that it had on it another egg of Coryphista meadii!  So now I’ll have two Coryphista caterpillars to look after.
