A fritillary feeding on butterfly milkweed (Asclepias tuberosa) flowers, St Bruno Provincial park.

A hairstreak butterfly feeding on a butterfly milkweed, Butterfly milkweed (Asclepias tuberosa) is a native to Quebec but is considered quite rare in the province, so finding one was unexpected. The flowers are very attractive to a range of insects. This butterfly was obsessed with it. It occasionally flew away a few feet, rested for a couple of minutes, and then flew back to it, but otherwise remained feeding on the same plant for at least an hour.
