The complete county distribution, spread across 7 Connecticut 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 lives underground in Connecticut’s lawns, fields, open woods, and other well-drained soils. Their raised surface tunnels and round soil mounds are much easier to find than the animal itself, including in grassy portions of Hammonasset, Bluff Point, and Barn Island. Broad, outward-turned forefeet distinguish a mole from any shrew or mouse.

Scattered records occur in every season, with several small peaks rather than one clear viewing period. Treat tunnel systems as the observation: digging one open rarely produces a useful sighting and unnecessarily disrupts the animal.
