Collection and habitat data.

Charaphloeus convexulus was found in various forest types in New Brunswick, including mature hardwood forests, an old red oak forest, mixed forests, a red spruce forest, and an old-growth red pine forest. However, this species was most frequently collected in hardwood forests. Most adults were captured in Lindgren funnel traps. One individual was captured with an aerial net during a warm evening. Adults were collected during April, May, and June (most during May). This species usually occurs under bark ( Thomas 1993).
