Collection and habitat data.

Philonthus aequalis occurs in wet habitats along margins of rivers and creeks, in swamps, marshes, and lake margins. Adults occur in flood debris and can also be collected by treading and sifting leaf litter in swampy forests ( Smetana 1995). Most adults from New Brunswick were found along river margins in drift material. One individual was collected from leaf litter on the margin of a vernal pond in a mixed forest. Adults were collected in May, June, and August.

Distribution in Canada and Alaska.
