Distribution, Habitat, and Field Biology of Somatochlora hineana (Odonata: Corduliidae)

Critical species of Odonata in North America

“…It has not been rediscovered in Ohio (Glotzhober & McShaffrey 2002) or Indiana (Curry 2001) despite special searches, but there is an anomalous 1978 record from northeastern Alabama (Tennessen et al 1995). Interestingly, it has been found that the larvae can survive winter or drought in crayfish (Cambarus diogenes) burrows (Vogt & Cashatt 1994;Cashatt & Vogt 2001). Genetic studies indicate several separated metapopulations (Purdue et al 1996).…”

Description of the larva ofSomatochlora hineanawith a key to the larvae of the North American species ofSomatochlora(Odonata: Corduliidae)

“…Recent attempts to confirm the presence of this species in Alabama, Indiana, and Ohio have been unsuccessful. Habitat and behavior were discussed briefly by Vogt & Cashatt (1994). It was listed as Endangered by the United States Fish and Wildlife Service in 1995 (Federal Register 60# [ 17]: 5267 -5272) because of its narrow ecological requirements and vulnerability to habitat degradation and destruction.…”

Contrasting Ozark and Great Lakes populations in the endangered Hines emerald dragonfly (Somatochlora hineana) using ecological, genetic, and phylogeographic analyses

“…For example, the known geographic distribution of extant and extirpated populations of the federally endangered dragonfly Somatochlora hineana Williamson (Odonata: Corduliidae) is depicted in Figure 1. The geographic distribution of this species is limited by restrictive habitat requirements that include wetlands with calcareous seepage flow (Cashatt & Vogt, 2001;Vogt & Cashatt, 1994), the presence of crayfish burrows that nymphs use as refugia (Pintor & Soluk, 2006;Soluk et al, 2000), and nearby meadows or pasture for adult foraging (Foster & Soluk, 2006 Table S4) cattail marshes, sedge meadows, and fens (Cashatt & Vogt, 2001;Foster & Soluk, 2006;Pintor & Soluk, 2006;Vogt & Cashatt, 1994), but these Hine's emerald dragonfly (HED) habitats will all be referred to as 'fens' in this paper as fens are the exclusive HED habitat in the Ozarks and the most common HED habitat in the Great Lakes region. Most fen habitat in the contiguous United States is found in the Great Lakes region.…”
