From: Drosophilids with darker cuticle have higher body temperature under light
Principle of temperature normalization. In this screenshot of a video taken with the FLIR camera, Drosophila santomea is on the left and Drosophila yakuba is on the right. The flies are surrounded by eight ellipses numbered 1 to 8. The regions denoted by “Freehand” delimit the areas covered by the bodies of the two flies monitored during the experiment. In this example, ellipses 4 to 7 were used to normalize the body temperature of the fly to the left, while ellipses 1, 2, 3 and 8 were used to normalize the body temperature of the fly to the right.
