I started off in the Erieau vicinity, covering the McGeachy Pond Trail and then the Rail Trail. There were lots of flowering plants, including Canada Thistle, Common Milkweed, Sowthistle, Common Yarrow and such. Except for the yarrow, most flowering plants are non-native, but the butterflies made use of what was available. The butterflies were scattered but not overly abundant.
There were a few Monarchs, but almost all were constantly on the move. This faded individual took a rest for a few moments before moving on.
(Summer) Azures were here and there.
A nice surprise, and perhaps my most interesting sighting of the day, were two Bronze Coppers. I don't think I have ever had them on this count before. They were quite fresh looking and cooperated nicely.
The Rail Trail is mostly shaded at this time of year, but did have a few sunny spots where a few butterflies hung out. I got my only American Lady of the day here.
Little Wood-Satyrs were more plentiful here than anywhere else I was over the day.
After enjoying a fairly productive time at this large milkweed patch, I went on my way leaving the other three to continue on with various spots. I made several stops at grassy/weedy fields in the Blenheim area, including some railroad track areas, the grassy field NE of Blenheim that has harboured several Dickcissel and Bobolink in the last few weeks, and ended up at a 40 ha pasture a little farther NE of Blenheim where I have had as many as 19 Dickcissels. But the windy conditions were getting a little out of hand, and with the exception of Monarchs fighting the wind somewhat successfully, there was very little else. I did find my one and only Black Swallowtail in a field of horticultural wildflowers. I tried several shots, but there was always too much movement. In a very brief lull this individual managed to hang on to a Wild Carrot (a.k.a Queen Anne's Lace) where I got one shot that was worth keeping.
There were other interesting sightings of winged things over the day, which just might make it into a future blog post.
