New Record Of Idana Marginata (Say) (Diptera: Tephritoidea: Ulidiidae) From Wisconsin, Daniel K. Young
New Record Of Idana Marginata (Say) (Diptera: Tephritoidea: Ulidiidae) From Wisconsin, Daniel K. Young
The Great Lakes Entomologist
Idana marginata (Say) was previously known from northeastern North America: Canada and the United States, west to northeastern Illinois and south to North Carolina. Herein, collection events are reported from Richland County in southwestern Wisconsin. This new state record significantly increases the known geographical distribution of the species to the west. The specimens were recovered from an unbaited Lindgren funnel trap during two intervals between 26 June and 28 July 2019.

River otter (Lontra canadensis) populations in North America have been the focus of significant restoration efforts. Wildlife management agencies, concerned about the unintentional take of river otters incidental to beaver (Castor canadensis) trapping, may recommend techniques to avoid capturing river otters. River otter avoidance techniques that are ineffective or diminish trap performance for beavers are undesirable. We conducted a field evaluation in 2015 and 2016 in Wisconsin to assess how two trigger configurations (offset and center) on body-grip traps would affect the incidental capture rate of river otters during beaver trapping. We also evaluated effects of …
