   More Colias News:  Mark Wynja went back to the location where he photographed a Clouded Sulphur

 (see August 22 Alert) and he found three ova – two of which have already hatched into tiny caterpillars.   

Mark adds that Steve Ansell mentioned that Clouded Sulphurs have recently shown up in the Lower Mainland and on the Sunshine Coast. 

   Mr E sends photographs of a geometrid caterpillar from Tahsis.  With a head like a pussycat, the caterpillar might be Biston or Pero.  Caterpillars of Biston are usually found in late summer;  those of Pero in the spring.  In spite of that, Jeremy Tatum writes, I’m inclined to agree with Mr E and I think this caterpillar looks more like Pero.
