The Ringed Boghaunter, Williamsonia lintneri, was first discovered in Maine in 1995. Since that time the Maine Department of Inland Fisheries and Wildlife (MDIFW) has conducted annual surveys to assess the distribution and status of the species in the state. The biology of W. lintneri has presented several challenges for surveyors because of its early and brief flight period (April 27-June 11 in Maine), its tendency to spend most of its brief adult life stage in forested uplands, and the difficulty of definitively distinguishing its exuviae from those of the ebony boghaunter (Williamsonia fletcheri) Ė a species with considerably more general distribution and habitat preferences in Maine. Nevertheless, surveys to date have improved our understanding of the habitat requirements and distribution of W. lintneri in Maine and resulted in: 1) the development of a habitat potential index to score wetland suitability, 2) the development of an evidence-based categorization of wetland breeding certainty, and 3) the identification of several previously unknown populations. The results of this work will be summarized and a wetland-specific conservation model will be proposed as a management tool for the conservation of W. lintneri breeding habitats.
