Collection and habitat data.

In New Brunswick, most adults were collected in red maple ( Acer rubrum L.) swamps, alder ( Alnus sp.) swamps, and eastern white cedar swamps, usually along vernal pool and brook margins, and in Carex marshes. One adult was collected from a seepage area along a river margin. Adults were sifted from moss and various kinds of grass and leaf litter. Elsewhere, specimens were collected from dead swamp grass and moss ( Smetana 1971a), leaf litter in a cedar bog, and a pitfall trap in a bog ( Smetana 1981). Adults in New Brunswick were collected in April, May, and June.

Distribution in Canada and Alaska.
