Oarisma poweshiek, the Poweshiek skipperling,
Description
Coloured dark brown on the upperside with an orange along the costa. The underside of the hindwings are dark grey with white veins.[4]
Wingspan is from 24 to 30 mm.[4]
Behaviour
The Poweshiek skipperling emerges in late June or early July and exists in the adult form for approximately a two-week period. During this time the skipperling nectars on a suite of flowers, mates and lays eggs. The larvae feed on graminoid plant species that possibly vary throughout the distribution of this species.[4]
Conservation status
The Poweshiek skipperling was a common prairie butterfly prior to 2005, but suffered a population crash between 2005 and 2015. The Poweshiek skipperling has a NatureServe ranking of G1 or critically imperiled.
In 2018, the Minnesota zoo began efforts to rear them in captivity, for release in the wild.[10][11] In 2022, the Minnesota zoo released over 100 individuals in to the wild.[12]
