Collection and habitat data.

Eucinetus morio was found in a variety of forest types in New Brunswick, including mature hardwood forests, an old red oak forest, old and mature mixed forests, an old-growth white spruce ( Picea glauca (Moench) Voss) and balsam fir ( Abies balsamea (L.) Mill.) forest, eastern white cedar ( Thuja occidentalis L.) forests, a mature (110-year-old) red spruce forest, and an old red pine forest. Most specimens were captured in Lindgren funnel traps deployed in the above forest types. Specimens with specific habitat data were collected from moist sphagnum (in eastern white cedar swamp), on polypore fungi on dead standing American beech ( Fagus grandifolia Ehrh.) and a dead standing Populus sp., and in powdery slime mold at the base of a tree. Lawrence and Newton (1980) reported the slime mold, Stemonitis axifera (Bull.) as a host for this species, and Weiss and West (1921) reported it from a Trichia sp. ( Trichiaceae ). This species has an amazing jumping ability, and adults often jumped out of a 15 cm high sifting box. Adults were collected during May, June, July, and August.

Distribution in Canada and Alaska.

ON, QC, NB, NS ( Campbell 1991a, Majka 2010). Majka (2010) newly reported Eucinetus morio from New Brunswick based on one specimen collected by P. Maltais in Moncton (Westmorland Co.). This is the most common species of Eucinetidae in New Brunswick.
