The complete county distribution, spread across 3 Delaware counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Eastern Moles spend nearly all their time underground in Delaware lawns, meadows, fields, and loose woodland soils. Raised surface ridges and fresh soil mounds are easier to find than the animal itself; Brandywine Creek’s uplands and well-drained ground away from the wettest coastal marshes provide likely habitat.

Evidence can appear year-round, with records most frequent from spring into summer. Surface activity often follows rain, but mapped sightings are sparse because an underground mammal rarely presents itself to observers.
