温度是决定昆虫生长发育速率的最重要的因子, 气候变暖能加快昆虫各虫态的发育, 导致其首次出现期, 迁飞期及种群高峰期提前. 陆生昆虫在环境太热时寻找一个阴凉潮湿的处所. 如暴露在阳光下, 它使自己处于体表受热面积最小的位置. 如太冷, 昆虫留在阳光下取暖. 许多蝴蝶在飞行前需展翅收集热量. 蛾在飞行前震动翅或抖动身体, 并藉毛或鳞片在身体周围形成一层空气绝缘层保住体热. 最适于飞行的肌肉温度是38～40℃ (100～104℉).
Temperature is the most important factor determining the growth and development rate of insects. Climate warming can accelerate the development of various insect states, leading to earlier emergence, migration and population to peak period. Terrestrial insects look a cool and humid place when the environment is too hot . If exposed to the sun, it keeps itself in a position where the surface area of ??the body is the least heated. If it is too cold, insects stay in the sun to warm up. Many butterflies need to spread their wings to collect heat before flying. Moths shake their wings before flying by shake the body, and use hair or scales to form an air insulation layer around the body to maintain the body temperature. The most suitable muscle temperature for flight is 38～40℃ (100～104℉).
