CommentsAdditional male specimens captured by the Invasive Species Program staff of Nic Zurfluh, of the Idaho State Department of Agriculture and myself during the week of July 20, 2018. Specimens were shipped to Susan Adams, PhD., U.S. Forest Service in Oxford, Mississippi on Aug 1 for species verification. Confirmation of species provided by Susan Adams and Chris Taylor via email on August 1 and 2, 2018. I would recommend considering this an established population based on the number of exoskeletons and live animals observed in and around the reservoir. In various creek channels and wetlands on the mud flats and within the east side of the Blacks Creek Reservoir
