The High Knob Mimic MillipedePaul Marek
Brachoria insolita individuals are about 42.1 mm long and 9.3 mm wide (females 45.3 mm X 10.6 mm). Color: 3-spotted yellow (shown above), orange (rare) or red (rare).

HabitatBrachoria insolita individuals have been collected in Appalachian mixed mesophytic deciduous forests comprising predominately maple and tulip poplars. Individuals were found beneath layers of decomposing leaf material. Many other xystodesmids co-occur with B. insolita. Note: Individuals of B. insolita may easily be confused in the field with Apheloria virginiensis corrugata, B. cedra, B. dentata and B. hoffmani due to similarity in color patterns (around High Knob all of these species can be found as mimics).
DistributionBrachoria insolita is only known from about five localities in two counties in Virginia, Norton City and Wise. Brachoria insolita occurs in the Stone Mountain highlands where it co-occurs with B. cedra, B. dentata, and B. hoffmani forming a component of a Müllerian mimicry ring with them.
Conservation statusBrachoria insolita is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.
