Figure S3: Heating rates of Calopteryx splendens and C. virgo in a laboratory experiment

Result of from a repeated-measures analysis of a laboratory experiments aimed to investigate species-differences in heating rates of Calopteryx splendens (open symbols, dashed line) and C. virgo (closed symbols, solid line). Least square means ± 95 Confidence Intervals (CI:s) are depicted and have been estimated from the model in Supporting Table S5. Pre-heating and post-heating show the thorax temperatures of both species at the start of the experiment and after three minutes under a heat lamp.
