I saw this large stinkbug (close to 15 mm I'd say), on the wall of the interpretive centre. A few days ago in the west end, I saw a gorgeous, brilliant green Large Green Stinkbug. It was a sunny but very cold day, particularly in comparison to what we've been experiencing. It was -19 with windchill this morning, and it felt only slightly warmer standing in the wind later in the day. So I was surprised to see this guy and a bunch of cluster flies (I think, I didn't really look closely). But the wall of the building would be warm.
