Gray Petaltail (Tachypteryx thoreyi is Maryland's only representative of the ancient Petaluridae, a family of primitive dragonflies that now exists as a handful of geographically disjunct relict species on several continents. This large, distinctive species breeds in forested seeps, including steep hillside seeps, and ranges into nearby forest, where they often perch on tree trunks or other vertical surfaces, including people. The peculiar larvae are semiterrestrial, and live in muddy leaf litter in or near the seep (Paulson, 2011). Gray Petaltail is an S3 (watch list species) in Maryland.

Tachopteryx thoreyi, commonly known as the gray petaltail and Thorey's grayback, is a species of dragonfly. It is native to the East Coast of the United States from New York to Florida, and west to Texas. This species is the only member of the monotypic genus Tachopteryx.[2]
The gray petaltail lives in highlands, woodlands, and deciduous forests with permanent seeps, often indicated by the presence of skunk cabbage and ferns.[3]
The gray petaltail is primarily gray and black in color; the thorax is usually entirely gray, while the abdomen is gray and black. The adult is 7.1 to 8.0 centimeters in length.
