The complete county distribution, spread across 13 Pennsylvania counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Pennsylvania has 31 eastern mole records since 2000, all of them iNaturalist observations, a small number for an animal that spends almost its entire life underground and is nearly blind, sensing earthworms and grubs by touch rather than sight. Most people never see the mole itself, only the ridged tunnels and molehills it leaves behind in lawns and gardens.

NatureServe ranks it S5, secure, in Pennsylvania, and the state’s occasional showing among tracked mammals backs that up. Records peak in July, with a smaller rise in September, though 31 records spread across the year are too few to read much into. Most come from the southeast, led by Philadelphia and Chester counties, and Marsh Creek State Park is the only named place with more than one, though molehills anywhere in the state’s lawns and gardens are just as good a sign.
