   Aziza Cooper writes:  On July 18, a Mourning Cloak flew by and five or more Woodland Skippers were at a house on Old West Saanich Road, on the east side of Observatory Hill.

This tiny moth was in the kitchen today.

Jeremy Tatum writes:  I believe the small moth is a tortricid.  If anyone knows what it is, please let us know.

Jeff Gaskin writes:  I had pretty dismal results at Swan Lake today, July 18.  I had just 8 Lorquin’s Admirals and 6 Cabbage Whites there – nothing else.  At Cecilia Ravine Park I saw 7 Cabbage Whites,  1 Lorquin’s Admiral and 2 Western Tiger Swallowtails.
