Checklist of the Dragonflies and
Damselflies of Patuxent Research Refuge
CHECKLIST OF
THE DRAGONFLIES   AND DAMSELFLIES OF THE PATUXENT RESEARCH REFUGE
(Prince Georges and Anne Arundel Counties, Maryland)

This checklist covers the known dragonflies and damselflies (odonates) for all of the Patuxent Research Refuge.  In identifying
odonates, focus on the color and markings of the abdomen, thorax, wings, and head.  At rest, how does the odonate hold its wings?
Generally, dragonflies rest with their wings horizontal to their body and damselflies rest with their wings together or nearly so above
their body. Also remember that the males and females are frequently different colors.

The seasonal occurrence and likelihood of seeing the adults 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.

Please report any sighting of dragonflies or damselflies marked with an asterisk (*), or species not listed, to refuge staff.

Please do NOT harm or collect any species!
