1. 流萤即萤火虫，晚上出来活动，并能发出荧光，这与萤火虫体内特殊物质的综合作用有关。萤火虫体内有虫荧光素这种特殊的发光物质，由三磷酸腺苷（ATP）激活后，又被进入体内的氧和体内的酶氧化。这种氧化反应导致兴奋状态而发光。然后，光又经多脂肪细胞的下层反射出来。萤火虫发出的荧光不仅是表达交流的方式，同时也是一种性召唤。

1. The firefly, also known as the glowworm, is active at night and can emit bioluminescence, which is related to the combined action of a special substance within the firefly. The firefly possesses a unique luminescent substance called luciferin, which, upon activation by adenosine triphosphate (ATP), is then oxidized by oxygen entering the body and the enzymes within the body. This oxidation reaction leads to an excited state and the emission of light. The light is then reflected out from the lower layer of the adipose cells. The bioluminescence emitted by the firefly is not only a means of expression and communication but also a form of sexual attraction.
