   Jeremy Tatum sends three photographs taken today.  He writes:  I am gradually trying to learn to identify our pugs.  Eupithecia ravocostaliata is one of the larger ones, with distinctive markings, and relatively easy to identify – although even it has a look-alike (E.. nevadata).  This one was on the wall of my Saanich apartment this morning.


  In yesterday’s posting, I showed the pupa of a Sara Orangetip with the colour of the wings of the imago showing through.  Sure enough, the butterfly – a male – emerged today.  After photographing it, I took it out to Munn Road, where the caterpillar came from last year.


  Finally, a snail, Cepaea nemoralis, from McIntyre Reservoir.
