Like other members of its genus, it is likely associated with herbaceous host plants, though specific host associations for this species remain poorly documented. The species was described by Malloch in 1914 based on specimens from Vermont.
Apterocyclus munroi
Apterocyclus munroi is a species of stag beetle in the family Lucanidae. The species was described from four specimens collected on Kauai, Hawaii in 1897. No confirmed observations have been made since the original collection, and the species is considered possibly extinct. It belongs to a genus of flightless stag beetles endemic to the Hawaiian Islands.
Attaneuria ruralis
Giant Stone, Enigmatic Stone
Attaneuria ruralis, commonly known as the Giant Stone or Enigmatic Stone, is a stonefly species in the family Perlidae. It was historically documented from larger rivers in Ohio but has not been collected in the last 50-60 years, raising concerns about local extinction. The species possesses a long life cycle of 1-2 years, which increases its vulnerability to population loss. Its distribution extends across the southeastern and midwestern United States.
Chrysotus arkansensis
Chrysotus arkansensis is a species of long-legged fly in the family Dolichopodidae. It was described by Van Duzee in 1930 based on six specimens collected from Fayetteville, Arkansas in 1906. As a member of the genus Chrysotus, it belongs to a diverse group of small to medium-sized predatory flies. The species remains poorly known, with no subsequent records or biological studies published since its original description.
