Acroneuria flinti Stark & Gaufin

Flint’s Common Stonefly (Acroneuria flinti)  

Flint’s Common Stonefly, described in 1976, is known only from the type locality, a stream in Fairfax County in northern Virginia, USA, where the species apparently was collected once in 1962.

Any efforts to relocated the species were unsuccessful so far and it might indeed be extinct.

Coptotriche perplexa (Braun)

Chestnut Clearwing Moth (Coptotriche perplexa)

The Chestnut Clearwing Moth, as its vernacular name implies, was adapted to the American Chestnut tree (Castanea dentata (Marsh.) Borkh.) as its sole larval host plant. The populations of that tree species broke down after the introduction of a fatal disease, the chestnut blight, caused by a fungus (Cryphonectria parasitica(Murrill) M. E. Barr), that was accidently brought to northern America in the 19th century. The loss of large stands of American Chestnut led to the extinction of several insect species that had adapted to them as their host plant.

This species, however, is only known from the type series, and was only aver found near Falls Church in Virginia; it may turn out to be identical with (Coptotricha zelleriella (Clemens)), a very widespread species that appears not to be adapted to any specific plant species.

Epioblasma haysiana (Lea)

Acornshell (Epioblasma haysiana)

The Acornshell aka. Acorn Pearly Mussel was described in 1834; this species inhabited the drainages of the Cumberland- and the Tennessee Rivers in Alabama, Kentucky, Tennessee and Virginia, USA.

The species died out due to habitat destruction and pollution; the last known individuals died in the 1970s due to exposure to domestic sewage.
