Checklist of Dragonflies and Damselflies of the
Potomac River Corridor and its Associated Wetlands
This checklist covers the dragonflies and damselflies of the Potomac River Corridor and associated wetlands from Theodore
Roosevelt Island to Harpers Ferry.  This includes the C&O Canal NHP, George Washington Memorial Parkway, Harpers Ferry NHP,
McKee Beshers WMA, Great Falls National Park, Riverbend Park, and all points in between.

The seasonal occurrence and relative likelihood of encountering the adults presented in this checklist are very general.  Some
dragonflies are present in good numbers but are not likely to be encountered by a general naturalist.  Other species are very
conspicuous and even though they are few in numbers standout and are noticed.  Seasonal occurrences presented are also
generalized because it is often only when males mature and return to the breeding grounds that they are usually noticed.

ADULT FLIGHT SEASON
(S) = usually noticed only in the spring
or early summer
(F) = usually noticed only in the late
summer or fall
If not marked can be found through out the season

LIKELIHOOD OF ENCOUNTERING ADULTS
(A) = Abundant and conspicuous in
appropriate habitat

(C) = Certain to be seen in suitable
habitat

(U) = Present, but could easily be
missed in suitable habitat

(R) = Not likely to encounter

(H) = Historical records only
