Ross Layberry, one of three authors of The Butterflies of Canada, recently released over 100 Milbert’s Tortoiseshell butterflies on his property near Fitzroy Harbour. He reared them from a nest of larvae which he collected near Cornwall on May 10. Each has been marked on the underside, in the centre of the hind wing, with a small spot of white.
He would appreciate you keeping a lookout for these marked butterflies over the next couple of months. There is no need to capture the butterflies, just note if you see one with a white spot at the centre of the underside of the hind wing, and the coordinates or location of your sighting. If you see a marked Milbert’s Tortoiseshell butterfly, please contact Ross by email at: rosslayberry@yahoo.ca.
