Collection and habitat data.

Habrocerus capillaricornis has been reported from forested areas under bark, in litter, in fungi ( Assing and Wunderle 1995) and from compost (Brunke et al. 2011). In New Brunswick, this adventive species was common among decaying leaves in a pile of leaves made the previous year. Other adults were observed among a pile of decaying corncobs and cornhusks nearby and from compost (Webster, unpublished data). Adults were also found under bark of spruce in a woodpile, in decaying fungi, in the wall of a beaver lodge and at a black-light trap. Adults were collected during April, May, July, and August.
