Bog Buckmoth (Hemileuca spp.)
Bog buckmoths are a unique, day-flying silk moth species in the family Saturniidae. they have stunning white, black and orange markings with a large wing span. The larval stage of this species is dependent on a bog plant called bog buckbean. The diurnal habits, physical attributes, and specialized habitat of the bog buckmoth make it a species of interest. Natural and human caused impacts have reduced the specialized habitats needed for the survival of bog buckmoths. Due to the rarity of this species, bog buckmoths are considered an endangered species in New York.
Bog buckthorn moths are only found in rare and distinctive wetlands called calcareous fens where its primary host plant the bogbean (Menyanthes trifoliata)grows. Below are two photos that depict the bogbean plant and a calcareous fen habitat.
Bog buckmoths are sparsely distributed and are only found in ten colonies throughout the world with six of those colonies located in Oswego County, NY , and the other four in eastern Ontario, Canada. In NY, bog buckmoths can be found in wetlands sheltered by the eastern Lake Ontario dune network.
