摘要: In a bivouacked swarm of honey bees, most individuals are quiescent while small minority (the scouts) active in choosing the swarm's future nest site. This study explores way which members warm their flight muscles for take-off when eventually decamps. An infrared camera was used to measure thoracic (flight muscle) temperatures individual bees on surface cluster. These generally coolest swarm. The warming surface-layer occurred mainly last 10 min before take-off. By time began, 100% had heated at least 35°C, is sufficient support rapid flight. Take-offs began only few seconds after all warmed but exactly how take-offs triggered remains mystery.
