    Monthly Butterfly Walk.   Sunday June 5.  Meet at the top of Mount Tolmie at 1:00 p.m.  All welcome!   We decide on a destination by mutual consent when we meet at Mount Tolmie.  One possibility that has been mentioned is Boas Road, near Spectacle Lake for Boisduval’s Blue.


   Aziza Cooper sends pictures of a bombyliid fly from the field east of Lochside Trail, south of Lohbrunner Road, June 1;  and a damselfly along the railroad tracks at Goldstream, May 30.  Jeremy Tatum writes:  I’ll have a stab at identifying them, though I’d be glad of confirmation from anyone who knows these insects.  The fly is Anthrax sp.

As for the exact species, I can’t be sure, but I’d guess either A. georgicus  or A. analis.  These may be synonyms for the same species. The larvae are said to be parasitoidal on tiger beetles.  I think the damselfly is the Western Red Damsel.
