    This is a subterranean species, preferring to live in other animals' burrows. It may also burrow in sandy or loamy soils.

    How to Find

    This is a nocturnal species. It usually only is seen above ground in plowed fields or after heavy rains. On a post-rainy evening, go out to open areas near woods. Look in rodent burrows or rotted tree roots. They may also be found crossing roads.

    Distribution in Maryland

    Found only on the western shore of the Coastal Plain and adjacent Piedmont counties.
