Jeremy Tatum writes:  On May 26 I showed a photograph of an egg of the geometrid moth Coryphista meadii.   Today the egg hatched.  Here is the empty egg shell:

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.

    Viewers may recall Rosemary Jorna’s photograph of a Ceanothus Silk Moth Hyalophora euryalus ovipositing, May 6.  Rosemary writes that the caterpillars have now hatched, and she sends photographs of the tiny first-instar caterpillars feeding on Thimbleberry Rubus parviflorus.

  Jody Wells sends photographs of a dragonfly from Pendray Farm, near Victoria Airport, May 25.  Dr Rob Cannings writes:  This is a female Cardinal Meadowhawk  Sympetrum illotum. Note the brown marks at the base of the wings and the white lateral thoracic spots.  Just the right time for them to be appearing, although the first ones might have been a bit late this cool spring. This one has recently emerged, thus the muted colours and the rather filmy wings. Looks healthy and intact, though.

   Jeremy Tatum writes that there was a Painted Lady (butterfly) on the Mount Tolmie reservoir at 4:45 this afternoon.  [Viewers of this site will have learned recently (May 21) that there is also such a thing as a Painted Lady beetle!]

    A correspondent sends a photograph of a pristine-fresh Spilosoma virginica seen in East Metchosin yesterday.  This is the adult of the familiar Yellow Woolly Bear caterpillar that we see in late summer.
