I am a graduate student at the University of Oklahoma, studying speciation and reproductive isolation in Enallagma damselflies. I am looking for potentially hybridizing species in the United States. I have read about male specimens with clasper morphology intermediate between two species, suggesting the possibility of hybrids, especially between E. carunculatum and E. anna, E. civile and E. anna, and E. civile and E. carunculatum.
I am interested in investigating reproductive isolation between these three species and am looking for sites in the contiguous US (or possibly Canada) where at least two of them occur. I welcome any recommendations of sites where two of these species are accessible and abundant in the summer, as well as accounts of any putative hybrids or interspecific tandems you may have found between these or other species.
