Striped skunks turn up in 770 Illinois records, spread from Cook County’s preserves and suburbs down to Shawnee National Forest and the fish and wildlife areas around Mermet Lake. Prairie restorations such as Midewin National Tallgrass Prairie and Nachusa Grasslands anchor the named picture, but the species itself is a creature of edges wherever it occurs.
An omnivore with a famous defense
The skunk does most of its hunting after dark, shuffling along field margins, fencerows, and creek banks while it roots out beetle grubs, crickets, mice, eggs, and fallen fruit. Much of that food comes from digging, and the small cone-shaped holes it leaves in lawns and pastures are often the clearest sign of one nearby. Its best-known trait is the musk it sprays from glands beneath the tail, a deterrent reliable enough that a threatened skunk stamps and warns before it spends a shot.
Winter quiet, spring courtship
Skunks are not true hibernators, but in Illinois’s coldest weeks they hole up in dens, often several sharing one, and venture out only in mild spells. The record reflects that rhythm, sinking in January and lifting sharply in February, when the breeding season puts males on the move. From spring through fall the counts stay steady, matching the months when insects are abundant and young skunks trail their mother on nightly rounds.
Status in Illinois
NatureServe ranks the striped skunk S5, Secure, in Illinois, and the species is native to the state. USGS NAS does not list it as nonindigenous here.
