Overview
Distribution
Global Range: The species occurs throughout the eastern and southwestern U.S., reaching Canada only in southern Ontario, northeast to near Hamilton, and in southern Manitoba and southeastern Saskatchewan. The maps in Opler and Malikul (1992) showing Quebec records and in Holmes et al. (1991) showing records throughout southern and eastern Ontario are in error, owing to confusion with icelus. At present, brizo is known to occur in only three areas of southern Ontario: Lambton County (Pinery Provincial Park area), Norfolk County (St. Williams area), and the south shore of Lake Ontario (Hamilton to Grimsby).

Migration
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Unlike most caterpillars Hesperiidae have distinct heads and the E. brizo's head is brown with an orange spot.[3]
