Laboratory experiments on heating rate differences of male and female Calopteryx splendens and C. virgo

Data come from a laboratory heating experiment on field-caught male and female Calopteryx splendens and C. virgo during 2009 and 2010, from two field localities: "Klingavälsåns Naturreservat" and "Höje Å, Värpinge", both in southern Sweden. Thorax temperatures were measured using IR-camera prior to heating and after three minutes under a heating lamp. Statistical analyses are provided in Table S5 and the species-specific differences in heating rates are illustrated in Figure S3.
