这种非华丽的环状蝴蝶，Coenonympha inornata，它的活动受到温度的高度限制，即使在晴朗的日子里，它的大部分时间也可能会停飞。这些侧篮的体温调节会消耗它们大部分的时间；雄鱼在晒太阳和飞行之间交替，温度在16度。C花了73%的时间晒太阳，只有27%的时间在飞行。另一方面，在较高的环境温度(Ta)下，它们大部分时间(80%)都是在飞行中度过的。在野外对活跃的蝴蝶进行长达52分钟的跟踪，以确定觅食行为、交配成功和体温调节的时间投入。觅食是它们飞行活动的一个次要组成部分。大多数飞行活动都与寻找配偶有关。在野外测量了绑在允许飞行和晒太阳行为的热电偶上的个体的胸部温度。在低Ta下晒太阳可以保持比连续飞行时更高的胸部温度，然后蝴蝶在追逐配偶时采取坐着等待的策略。相反，在高Ta的情况下，他们使用的是寻找配偶的策略。
The inornate ringlet butterfly, Coenonympha inornata, is highly constrained by temperature in its activity, and even on sunny days may spend a major portion of its time grounded. Thermoregulation in these lateral baskers can consume the major portion of their time; males alterante between basking and flying, and at 16.degree. C spend 73% of their time basking only 27% of their time flying. At high ambient temperatures (Ta), on the other hand, they spend most (> 80%) of their time in flight. Active butterflies were followed for up to 52 min in the field to determine foraging behavior, mating success, and time investments for thermoregulation. Foraging was a minor component of their flight activity. Most of the flight activity was associated with mate-seeking. Thoracic temperatures were measured in the field on individuals tethered to thermocouples that permitted flight and basking behavior. Basking at low Ta allowed the maintenance of higher thoracic temperatures than could be maintained in continuous flight, and the butterflies then adopted a sit-and-wait strategy in mate chasing. In contrast, at high Ta they used a search strategy for mate seeking instead.
