Invasive Species: Yellow Flag Iris

   Not all pretty photos show pretty things: an invasive Yellow Flag Iris (Iris pseudacorus) growing by the Millstone River at Bowen Park in Nanaimo, British Columbia, Canada

   Many regions have invasive plant species that have been “released” purposely by people or have escaped from gardens. These invasives often spread into areas where they force out native species and otherwise change the ecology of the area. Many are familiar with the spread of English Ivy through Metro Vancouver forests and Scotch Broom (Cytisus scoparius) on Vancouver Island.

   The Yellow Flag Iris (Iris pseudacorus) is also an invasive species, and is native to Europe, western Asia, and northwest Africa. This photo shows a flowering Yellow Flag Iris on the banks of the Millstone River in Nanaimo, British Columbia. While this is one individual plant the species can spread and cover entire wetlands and completely displace native species. Due to continued popularity in garden centers Yellow Flag Iris has spread widely on Vancouver Island, Metro Vancouver and the Fraser Valley, and even into the Okanagan and Kootenay regions of British Columbia.

   If you grow some of these in your backyard, it may be a good idea to destroy them to avoid further environmental damage.

Backyard UFO

I might have a BSc. in Biological Sciences but I have no idea what this critter is. It did briefly land on this iris leaf, however.

EDIT: Some variety of Leafhopper is my guess.
