From the Canadian Broadcasting System (July 10, 2013):

Monarch butterflies have been tough to come by in southern Ontario so far this summer.

Early July is normally the time of year when the black and orange butterflies start showing up . , ,

The Ojibway Nature Centre in Windsor (Ontario) held its annual butterfly count July 7 and spotted just one adult monarch.

Vic Bernyk owns Native Trees and Plants, a hobby nursery in Amherstburg, Ont., that specializes in creating butterfly gardens. He has yet to see a monarch. . . .

Some butterfly experts and enthusiasts are blaming changing weather patterns and drought in the U.S. for the lack of monarchs. Others blame herbicides for wiping out their natural habitat, namely milkweed.

Seven months later, in Feb 2014, and it’s beginning to look serious.
