“…No documentations for the species have occurred in Alabama or South Carolina since 1995 and 1977, respectively (Figure 1). Though the adult was taxonomically described in 1933, it was not until 2019 that the nymph was morphologically described; even so, the description remains incomplete, being solely based on the reared neotype, the biological specimen used for the description of the nymphal stage of this species (Tennessen, 2021;Williamson & Gloyd, 1933). Therefore, all field observations of this species have been of adults; nymphs have never been collected in the field.…”

Globally, freshwater ecosystems and the organisms that depend on them are at risk. Dragonflies and damselflies (collectively, “odonates”) have a history of being used as bioindicators of freshwater habitat quality due to their wide range in environmental sensitivities across species and because they are relatively accessible. However, the nymphal stage is severely understudied compared to the adult stage, which inhibits conservation efforts. Somatochlora calverti is a rare species of dragonfly in the family Corduliidae; members of the genus Somatochlora are notoriously difficult to find and collect in the field as nymphs and adults. Somatochlora calverti is known primarily from the Florida panhandle but has been documented in Alabama, Georgia, and South Carolina. The nymph of this species is speculated to use seepage streams analogous to sympatric congeners; however, the nymph has never been collected in the field and, therefore, its specific microhabitat is unknown. We conducted a review from a suite of informational sources to generate a holistic consensus on what is defined to be suitable reproductive habitat for S. calverti. Sources identified eight major environmental characteristics that are likely to harbor S. calverti: shallow seepage streams, including steephead ravines, with undercut banks and mats of Sphagnum moss adjacent to intact sandhill forest. These ecosystems are being lost and degraded by anthropogenic activity, which has considerable impacts on the persistence of habitat specialists, including S. calverti, and managers’ ability to conserve them.

The genus 14Zilliamsonia (Davis I9I 3 is composed of two littleknown species: lintneri (Hagen 1878) and fletcheri (Williamson 1923). Both are rather similar with respect to their early flight season and their habitat preference, lffilliamsonia lintneri is recorded in the literature from only four northeastern states of the U.S.A.: Massachusetts, Rhode Island, New York, and New Jersey. I4/illiamsonia fletcheri has a larger and more northern distribution which includes the states of Maine, Massachusetts, New York, and Michigan, and four provinces of Canada: Manitoba, New Brunswick, Ontario, and Quebec. Of lJ/illiamsonia lintneri, Howe (I923) commented "The dates, as will be seen, range from April to June 4 (sic) and
