Mustard White butterfly / Pieris oleracea

Mustard White butterfly / Pieris oleracea
Think I've found the ID! I believe this is a Mustard White butterfly / Pieris oleracea. Last night, I tried to find the ID for this plain white butterfly, but no luck. I couldn't remember if it is simply a spot-less Cabbage White or something different. Seen in Brown-Lowery Provincial Park.

"The Mustard White is found though out the boreal region of Canada. It is found in both deciduous and coniferous forest. There are two generations per year in Alberta, the first is out in mid-May and the second in July. The dark under wing veins may be reduced (ie pale) or absent in the second summer generation. (Bird et al, 1995 & Acorn, 1993)." From Insects of Alberta.

It was the annual May Species Count on 28 and 29 May 2016. My group's Saturday Count was down in Fish Creek Provincial Park, Votier's Flats and Shaw's Meadow. On Sunday, our usual small group (six of us in two cars) covered an area SW of the city - which happens to be one of my favourite and most visited areas. We had a great day, stopping at a few wetlands and calling in at Barb Castell's acreage where she usually has amazing birds to show us. Several special species were missing, but we were delighted to watch a teeny Ruby-throated Hummingbird. We stopped at Brown-Lowery Provincial Park and ate our picnic lunches and then did a short walk to look for Calypso Orchids. I took too long to try and get a sharp photo of a group of fungi that I missed the orchids, but that was OK, as I have seen them plenty of times before.

After the Count came to an end, I drove a few of the back roads again, taking a few more shots of the Wilson's Snipe.

I will add the final list from our leader, Gus Y - 70 bird species seen, wow!

"The count goes May 28-29: Calgary birders have been out in force every May since 1979, contributing to a broad census of the constantly changing patterns of bird distributions in North America. Last year (2015) we found 212 species. The count circle is the same as previous years, extending from Olds to Nanton, and from Exshaw to Standard, and includes a variety of environments." From NatureCalgary.
