Monarchs Streaming Today Along North Shore of Lake Ontario

East of Toronto, from Port Hope to Colborne, in spite of initial overcast weather, monarchs still arrived from the north and east, and struggled in westerly winds. Day initially overcast but a few monarchs observed flying anyway and trying to make progress. About 1 pm, the sun came out. Temperature about 68 F. In one large field near Grafton found one 5th instar caterpillar and in one large patch of clover with 12+ monarchs.

Monarchs seen following the Lakeshore Road as I drove east. Near Lakeport, in two large fields filled with hundreds of yellowing milkweed plants with chewed tops, lost count after 50 monarchs. Again purple clover flowers the nectar source of choice. Not much else left. Some monarchs had plump abdomens. Photos posted to Monarch Butterfly Fund Facebook site.
