Gray Petaltail Tachopteryx thoreyi (Hagen, 1858)S3 (Watch list)

Status:

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.

There are 98 records in the project database.
