Somatochlora calverti

Williamson & Gloyd, 1933

Calvert's Emerald, Andre Flies

Somatochlora calverti is a rare, range-restricted in the Corduliidae. It is to the southeastern United States, primarily known from the Florida panhandle with scattered records in Alabama, Georgia, and South Carolina. The is a associated with shallow seepage streams and steephead ravines. Its nymph has never been collected in the field, and its reproductive microhabitat remains speculative based on analogy to sympatric .

Identification

Members of the Somatochlora are notoriously difficult to find and collect in the field as both nymphs and . Adults can be distinguished from other emerald dragonflies by their southeastern U.S. distribution and association with seepage stream . Specific diagnostic morphological features for S. calverti are not documented in the provided sources.

Habitat

Shallow seepage streams, including steephead ravines, with undercut banks and mats of Sphagnum moss adjacent to intact sandhill forest. Wikipedia also lists rivers and swamps as natural .

Distribution

to the United States. Primarily known from the Florida panhandle; also documented in Alabama, Georgia, and South Carolina.

Life Cycle

typical of Odonata: , nymph (naiad), and stages. The nymphal stage is speculated to use seepage streams analogous to sympatric , though the nymph has never been collected in the field. Duration of nymphal development is unknown.

Behavior

Members of the Somatochlora are notoriously difficult to find and collect in the field.

Ecological Role

Used as a bioindicator of freshwater quality due to environmental sensitivity. As a habitat dependent on intact seepage stream , its persistence indicates ecosystem integrity.

Human Relevance

Of conservation concern due to degradation. The specific seepage stream it requires are being lost and degraded by anthropogenic activity, threatening the ' persistence. Known locally as "Andre Flies" in areas where it occurs.
