Chain-dotted Geometer in open fen

I came upon this somewhat worn Chain-dotted Geometer in an open fen along the Trans-Canada Highway yesterday. Distinctive features of this male include the highly pectinate antennae, yellow head and tegulae and checkered wing margins.

According to Bug Guide the larvae "feed on a variety of shrubs and trees: alder, bayberry, birch, blueberry, bog laurel, cranberry, fir, huckleberry, leatherleaf, maple, oak, pine, poplar, sweetfern, sweet gale, tamarack, white cedar, willow."
