I was familiar with the variety of grapes that grow wild over fence lines in southern Ontario but I wasn't aware until last year that there are wild grapes growing in Ottawa as well. The wild grapes that grow in Ottawa have smaller berries and looser bunches.
Once I could identify the leaves I was seeing the vines all over the place. Many of the plants do not seem to bear fruit. One such plant drapes itself over a glossy buckthorn growing by a telephone pole at the end of Kimdale.
The above plant doesn't produce any grapes because it is a male. Below is a closeup of its flowers with prominent stamens but lacking developed pistils. It has quite a pleasant scent.
Below is a small beetle I spotted on a grape leaf as I was inspecting the flowers. It turns out it feeds on grape vines so it was right at home.
