The degree of activity of H. virgaureae in the field is largely dependent on air temperature, solar radiation, and wind velocity. Solar radiation increases body temperature above ambient. The butterfly orientates its back towards the sun and exposes the dorsal surface of the wings. At high temperatures they close the wings thereby minimizing the surface exposed to the sun. The optimal body temperature lies around 35°C as was indicated by laboratory experiments. In cloudy and cool to fairly warm conditions the butterfly is inactive. In sunshine the butterfly basks at low radiation intensities or low air temperatures while feeding (in males also flying) predominates at full sunshine or very high air temperatures (around 30°C). Males fly 5-10 times as much as females. A change from unfavourable to favourable weather is followed by an immediate increase in activity of the butterfly, which enables the butterfly to utilize short periods of sunshine.
绿条弄蝶在野外的活动程度很大程度上取决于气温、太阳辐射和风速。太阳辐射会使体温高于周围环境温度。蝴蝶会将背部朝向太阳，露出翅膀的背面。在高温时，它们会合上翅膀，从而尽量减少暴露在阳光下的表面积。实验室实验表明，最佳体温约为35°C。在多云以及凉爽至相当温暖的条件下，蝴蝶不活跃。在阳光下，蝴蝶在低辐射强度或低气温时晒太阳，而在阳光充足或气温非常高（约30°C）时，进食（雄性还会飞行）占主导。雄性的飞行次数是雌性的5至10倍。天气从不利于活动转变为有利于活动时，蝴蝶的活动会立即增加，这使蝴蝶能够利用短暂的日照时间。
