V 143, 2012 Abstract Populations of Juniper Hairstreak (Callophrys gryneus [Hübner]) at Point Pelee National Park (PPNP) and Pelee Island have declined over time and are at risk of extirpation. We monitored them in the Red Cedar Savannahs of PPNP from late May–end August and on Pelee Island in early June. Two flights of adults occurred (maximum numbers observed daily in parentheses) from 29 May–12 June (4 at PPNP; 11 at Pelee Island) and 19 July–12 August (10 at PPNP) in and near intermediate-sized (mostly 5-7 m tall) junipers among the upper dunes of a small portion of the point’s western shore and in one clearing on Pelee Island. The primary nectar resource used by the first brood was Ptelea trifoliata L.; the second brood nectared infrequently on several floral species. |
