Dragonflies and Damselflies of the Lower Susquehanna River Watershed: Fragile Forktail nymph
The aquatic larval stage of a damselfly is commonly known as a nymph.  It feeds on small underwater invertebrates, then, as an adult, transitions to grabbing flying insects in midair.  While many species inhabit streams, Fragile Forktail (Ischnura posita) nymphs are found primarily in wetlands and small pools of water. This one was produced from eggs laid last summer among submerged vegetation in the susquehannawildlife.net headquarters pond.  In just a few weeks, it will climb a stem or cluster of leaves and transform into a colorful adult-stage damselfly known as an imago.  To see a photo gallery featuring this and other species of odonates found in the Lower Susquehanna River Watershed, click on the “Damselflies and Dragonflies” tab at the top of this page.
