Collection and habitat data.

Tetratoma tessellata was found in various forest types in New Brunswick. Adults were found in mature and old hardwood forests with American beech, yellow birch, and sugar maple, an old-growth northern hardwood forest with sugar maple and yellow birch, an old red oak forest, an old silver maple ( Acer saccharinum L.) swamp, an old eastern white cedar ( Thuja occidentalis L.) forest, a mature (110-year-old) red spruce stand, and an old (180-year-old) red pine forest. Most adults were captured in Lindgren funnel traps. One individual was collected from a slightly dried Pleurotus sp. on a dead, standing sugar maple. Most records reported from Nova Scotia by Majka and Pollock (2006) were caught with flight intercept traps in both coniferous and deciduous forests. Adults were collected during June, July, August, and September.
