I'm not asking what has been eating these leaves, am just posting this for appreciation. I was in Victoria last weekend and had an hour or so to walk around the Hillside area (is that a named area? I noted that there is a street called Mt. Stephen Ave, so maybe it's the Mt. Stephen area, a name that amused me a lot - it's a little hilly there, that's all). Anyway, these photos are all from around the same intersection, I think Kings and Asquith. The first is probably Aesculus hippocastanum, horse chestnut. Here is a very nice ornamental cherry, looks just like a real tree, either not grafted or low grafted; I've no idea what cultivar. Quercus garryana, Garry Oak; the third photo is an almost dead tree next to it. What surprised me was this beautiful Acer palmatum, Japanese maple, on the same intersection, with not even one bite missing from any of its leaves.
Well, of course it's not just in Victoria that the leaf eaters are happy. Here are Petasites hybridus from UBC Botanical Garden.
