Collection and habitat data.

In New Brunswick, Tritoma pulchra was found in a variety of forest types, such as mature hardwood forests, an old red oak forest, mixed forests, an old red spruce forest, an old red pine forest, an old-growth white spruce and balsam fir forest, and old-growth eastern white cedar forests. Most adults were collected from soft polypore fungi on logs and dead standing trees or captured in Lindgren funnel traps. A few individuals were collected by sweeping vegetation or sifting litter. One adult was found on flowers of meadow sweet ( Spiraea alba Du Roi) in a sedge marsh. Adults were collected during June, July, August, and September.
