leaf beetle

6101   Hi. My name is Teresa. I have an infestation of these bugs on one type of bush at my camp site in Saskatchewan Landing Provincial Park. (first noticed in mid to late June but still active as they move to new bushes) Do you know what they are?

This is a leaf beetle (Coleoptera: Chrysomelidae); it looks like Blepharida rhois, known as the sumac flea beetle. See https://tinyurl.com/y7w539sb for some images. Ed Saugstad, retired entomologist; Sinks Grove, WV.
