Rough Greensnake Opheodrys aestivus - Special Concern

Adult from Brown County
Subadult from Brown County

Identification: Rough greensnakes are bright green with yellowish underbellies and strongly keeled scales. They are very slender and move slowly through vegetation, often swaying like a vine to blend in. Most rough greensnakes are two to three feet (60 - 90 cm) long.

Similar Species: There are only two bright green snakes in Indiana and this is the species found in the southern and west-central parts of the state. The smaller smooth greensnake only occurs in northwestern Indiana; the two do not occur together in Indiana.

Distribution: Rough greensnakes occur primarily in southern Indiana, though they are occasionally found in western Indiana as far north as Parke County. They are an uncommon snake that may be in decline, though their cryptic coloration makes them difficult to study. This insectivorous snake is most abundant in densely vegetated edges; along hedgerows, thickets, and in vegetation overhanging bodies of water.
