Finally found a fall roost, near my home at Parklawn and Lakeshore, there are hundreds of Butterflies every day along the Lakeshore West in Toronto.. its amazing to see..

Editor's note: contacted observer for more details on this sighting

The time of day was aprox 4:00-5:00pm. I estimate there were well over around 1,000 butterflies, because they were spread out over 4-5 trees, with 5-10 still arriving every 5-6 mins.

There are lot's of nectar sources near by, there is actually a butterfly garden just east of their location, and a large park, with goldenrod that's just blooming.

The night time temp's were aprox 7-9 deg for the past week or so near me, sometimes dropping a bit lower than that.

The wind direction was SSW but I live right by Lake Ontario so it changes during the day several times.. They were sheltered from the wind, on the side of the tree's they were on. They were all facing East though, I was guessing that they were going to take advantage of the sun coming up the next morning.

I also want to add that I was up in the Georgian Bay (Balm Beach) area yesterday and there were tons of Monarch Butterflies heading out over the water heading South. I must have seen 100+ yesterday alone.

It's been a very very good year for them in Ontario, because we had great rainfall, and this brings tons of wild flowers everywhere. My husband was also on Georgian bay in a boat 2 weekends ago and the butterflies were landing on the boat to rest. He said there were hundreds of them out over the water too. He was in the Lion's Head area.
