Collection and habitat data.

In New Brunswick, Geodromicus strictus was usually found on exposed rocks and among cobblestones in the middle of clear, fast-flowing rivers or in moss on rocks adjacent to fast-flowing water near waterfalls. A few adults were collected from cobblestones in shaded brooks. Adults were collected by splashing rocks or cobblestones. This species was collected during June, July, August, and September.
