Look out for ‘marked’ Milbert’s Tortoiseshell Butterflies

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: .
