Ontario Monarch Migration in Progress

Over the past few days, hundreds of monarchs have been migrating
westward along the north shore of Lake Ontario, stopping to feed on
abundant milkweed at Presqu'ile Provincial Park (near Brighton),
Darlington Provincial Park (near Oshawa) and East Point Park (Toronto).

Buckeyes continue to be regularly seen. At Presqu'ile, 7 were seen last
Thursday. The ones I spotted were in perfect condition and there are
abundant amounts of their larval food plant in the park. (Previous to
this year, we only had about 5 sight records for buckeye!).

There was also a report at Presqu'ile of a gathering of red admirals on
a dead tree. Has anyone else seen such a phenomenon. The observer
suggested that they were getting ready to migrate across Lake Ontario.
