Checklist of Dragonflies and Damselflies
of Rock Creek Park
This checklist covers the dragonflies and damselflies of the Rock Creek National Park.

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

appropriate habitat
