I saw two mourning cloaks today, and two spring azures, the former expected, but the latter quite early. I would have been more surprised if I hadn't heard that someone else had seen a few elsewhere in Ottawa! No chance of a photo as they were moving constantly, sometimes low across the ground, other times twirling around each other high into the trees. In addition to the butterflies, there were good numbers of bees (Nomada, Andrenids, a few big bumblebee queens), flies, Asian ladybeetles, and a tiny, tiny Braconid wasp,
