description Delicate Emerald Overview
The Delicate Emerald, Somatochlora franklini, is a dragonfly in the family Corduliidae found across much of Canada and in parts of the northern United States. It inhabits sedge- and moss-filled fens, sphagnum bogs, and very shallow, well-vegetated waters, where its aquatic larvae develop before emergence. The species is associated with cool northern wetlands, and the loss or alteration of bog and fen habitat is a significant conservation concern for its populations.

What is the Delicate Emerald dragonfly's scientific name?
Its scientific name is Somatochlora franklini, a member of the Corduliidae emerald family. The species occurs across much of Canada and parts of the northern United States. [Xerces Society](https://xerces.org/endangered-species/species-profiles/at-risk-aquatic-invertebrates/delicate-emerald)
What habitat does Somatochlora franklini need?
It is associated with sedge- and moss-filled fens, sphagnum bogs, and shallow water with dense vegetation. That habitat is more specific than an ordinary open lake, so wetland changes can affect local populations.

Why is the Delicate Emerald difficult to spot?
Somatochlora franklini uses narrow wetland habitats and has behavior that can make it easy to overlook. Adults may feed away from the breeding fen, while the larvae develop in shallow aquatic vegetation. [Northwest Territories Species Search](https://www.gov.nt.ca/species-search/somatochlora-franklini)
