灯笼虫是最大的跳跃半翅目昆虫之一，体长可达44毫米，质量可达0.7克。 它们的重量是小型半翅目昆虫的600倍，而小型半翅目昆虫则利用弹射器机制来储存能量。在这些大得多的昆虫中，是否也有类似的机制推动跳跃呢？因此，从高速视频中分析了来自印度和马来西亚的两种灯笼虫（半翅目，Auchelurorhyncha，家庭Fulgoridae）的跳跃性能。运动学研究表明，跳跃是由两条后腿的快速同步运动推动的，两条后腿的大转子首先运动。后腿比前腿长20-40%，这是由于较长的胫。在最好的跳跃中，女性Kalidasa lanata需要5-6 ms才能加速到4.65 m s-1的起跳速度。 在这些跳跃中，成年人经历了77 g的加速度，需要4800 μJ的能量消耗和900 mW的功率输出，并施加400 mN的力。 胸部跳跃肌肉所需的功率输出为21，000 W kg−1，是肌肉最大主动收缩极限的40倍。 因此，这种跳跃性能需要在运动之前具有能量存储的功率放大机构，就像它们较小的亲戚一样。这些大型灯笼虫几乎是它们较小亲戚的等距放大版本，即使不是更高，也能达到相当的起飞速度，并且优于其他大型跳跃昆虫，如蚱蜢。总结：灯笼虫是一种大型昆虫，它们利用弹射器机制以高起飞速度跳跃，这与它们小得多的稻飞虱亲戚的表现相匹配
Lantern bugs are amongst the largest of the jumping hemipteran bugs, with body lengths reaching 44 mm and masses reaching 0.7 g. They are up to 600 times heavier than smaller hemipterans that jump powerfully using catapult mechanisms to store energy. Does a similar mechanism also propel jumping in these much larger insects? The jumping performance of two species of lantern bugs (Hemiptera, Auchenorrhyncha, family Fulgoridae) from India and Malaysia was therefore analysed from high-speed videos. The kinematics showed that jumps were propelled by rapid and synchronous movements of both hind legs, with their trochantera moving first. The hind legs were 20–40% longer than the front legs, which was attributable to longer tibiae. It took 5–6 ms to accelerate to take-off velocities reaching 4.65 m s−1 in the best jumps by female Kalidasa lanata. During these jumps, adults experienced an acceleration of 77 g, required an energy expenditure of 4800 μJ and a power output of 900 mW, and exerted a force of 400 mN. The required power output of the thoracic jumping muscles was 21,000 W kg−1, 40 times greater than the maximum active contractile limit of muscle. Such a jumping performance therefore required a power amplification mechanism with energy storage in advance of the movement, as in their smaller relatives. These large lantern bugs are near isometrically scaled-up versions of their smaller relatives, still achieve comparable, if not higher, take-off velocities, and outperform other large jumping insects such as grasshoppers. Summary: Lantern bugs are large insects that jump at high-take-off velocities using a catapult mechanism that matches the performance of their much smaller planthopper relatives
