Despite a previously cool night, the weather was hot and sunny as a team of seventeen completed this week's survey. Insects are poikilothermic and cannot maintain their internal temperature as we do. Instead, they often employ behavioral thermoregulation. The dragonfly shown below is obelisking, which shades its abdomen to prevent overheating, while the two butterflies in the next images are basking to achieve the opposite effect.
