This was a fairly large one, probably a female, and was hanging around the edge of a temporary pond at the Bartel grassland, probably looking for Chorus Frogs, which were singing loudly while I was there today.

Two rows of alternating black spots or blotches on the side. Belly gray-green with dark spots along the edges. Usually a pair of light spots on top of the head.
Habitat: Former black-soil prairies, cultivated fields, pastures, wet meadows and marshes, and vacant lots.
Natural History: One of the most cold-tolerant snakes, often emerging from hibernation to bask on warm, sunny winter days. Mates in April or May and gives birth to 5-30 young from August through early October. Newborn 15-25 cm TL. Does not bite as readily as the common garter snake when handled. Common prey are earthworms, slugs, and small amphibians. Predators include birds of prey, mammals, and other snakes. Large numbers are killed on roads each spring and autumn as they move to and from upland hibernacula.
Status: Common in the northern half of the state
