Collection and habitat data.

Magdalis barbita breeds in the trunks and branches of unhealthy Ulmus spp. ( Drooz 1985) and is also reported to be associated with Quercus and Carya ( Juglandaceae ) ( Blatchley and Leng 1916). Most adults from New Brunswick were reared from larvae or pupae collected from under barkof American or white elm ( Ulmus americana L.). Adults were captured during June and July in Lindgren funnel trap in an old silver maple swamp. Ulmus americana was present near the trap. The adult from Prince Edward Island was collected from young foliage of Ulmus americana during June.

Distribution in Canada and Alaska.
