Monarch butterflies clustered on a Sumac tree at Sam Lawrence Park in Hamilton, Ontario at 7:45 p.m. last night. A native of southern Ontario, the Sumac tree is next to about 40 butterfly bushes. The migration to Mexico occurs between Sept. 3 and 20 in this area of southern Ontario.
I also saw them the night before on Sept. 3 but they were in a different tree, but the trunk was damaged and tree laying down. (Vandalism?)
