   Jeremy Tatum  writes:   I have forwarded to Invert Alert a notice I had received about eButterfly.  If any of you are computer-oriented, we need someone to enter our butterfly observations to eButterfly.   Sonja Voicescu did it last year, and would be glad to help ease someone into doing it.  Let me know if you are interested.


    Jeremy Tatum writes:  Yesterday at 6:00 pm there were five Painted Ladies and a California Tortoiseshell  on the reservoir or around the Jeffery Pine on Mount Tolmie.  Although all of them seemed to be very worn, they could all fly strongly and chase each other vigorously.
