Habitats:

This is a snake of forests, old fields, swamps, dry sandy ridges adjacent to swamps, and agricultural fields adjacent to forests.


How to Find:

A relatively uncommon species on the coastal plain, but fairly common in forested rock outcrops of central and western Maryland. Their cryptic coloration makes them very hard to discern, even when you are looking right at them. Warning: this species is venomous! Do not attempt to capture. They will readily bite if provoked, and bites are extremely painful. Seek medical attention immediately if bitten.
