Some of the maple trees shedding their leaves in Thetis Lake Regional Park are playing host to some other species that is leaving interesting patterns on their leaves. I don't know whether these circular patches filled with black dots are the eggs of some insect or the the results of a fungus or....
Striking, but a little troubling as well. Hope the trees aren't in danger.
ReplyDeleteNice capture. Looks to me a fungus, but could be wrong.
