Elaterid 甲虫幼虫。 Pyrearinus termitluminans (sp.n., Costa, 1982.) 生活在巴西中部的白蚁丘中。每个幼虫都会在其头部后面的部分产生光。据观察，幼虫仅在雨季的头几周内发光，与蚂蚁和白蚁飞行的时间相同。有翼藻显然被白蚁幼虫的光所吸引，成为幼虫的重要食物来源。捕食和储存食物的行为以及生物发光现象显然是白蚁幼虫对短暂而丰富的食物脉冲的进化反应。猎物的吸引力可能是发光的原因，此前仅被提出过两次。
Elaterid beetle larvae. Pyrearinus termitilluminans (sp.n., Costa, 1982.) live in termite mounds in central Brazil. Each larva produces light in the segment immediately behind its head. Larvae were observed to luminesce only during the first weeks of the rainy season, the same times as the ant and termite alate flights. Alates, apparently attracted to P. termitilluminans larval lights, serve as an important food source for the larvae. The prey-catching and food-storing behavior and the phenomenon of bioluminescence are apparently an evolutionary response by P. termitilluminans larvae to a short, rich pulse of food. Prey attraction as a probable cause for luminescence has been suggested only twice before.
