Howard County Dragonflies and Damselflies

Photos from Field Work in Howard County 1996–present

Dragonflies and damselflies are not only beautiful but are masters of the air. Because part of their life history involves water, their presence can be an indicator of the health of these environments. Males, females, and immatures often look different, and the immatures of many species look similar to the females. In some cases, a photo of the exuviae (shed larval cuticle left behind after transformation to the adult stage) is included

Species that have been verified in Howard County, MD, are pictured below. Richard Orr, state odonate compiler, has verified identifications (some from specimens; others from multiple photographs—not all of which are posted)
