   Jeremy Tatum writes:   Ted Dobie’s caterpillar of Orgyia pseudotsugata, shown on July 21, and again when full grown in close-up on August 1 afternoon, has now pupated in a silken cocoon, incorporating some of the larval hairs.  The adult moth will probably eclode in a couple of weeks.

   Jeremy continues:  This morning I visited the Nature Houses at Swan Lake and in Goldstream Park, and I found one moth at each.  This one at Swan Lake:


Neoalcis californiaria (Lep.: Geometridae)  Jeremy Tatum

 

…and this one at Goldstream Park, confirmed by Libby Avis as a Peppered Moth Biston betulariaAfter millions of years of Darwinian evolution by variation and natural selection, this one seems to have evolved perfect cryptic coloration for a concrete background!
