I was entranced by a cluster of trees which were lit up by glow-worms.

我被萤火虫照亮的树丛迷住了。

A firefly is a type of beetle.

萤火虫是一种甲虫。

Fireflies sparked in the darkness.

萤火虫在黑暗中发光。

The glowworm isn't a worm.

萤火虫不是蠕虫。

The firefly is a holometabolic insect, passing through the stages of being an egg, being a larva, molting, and pupation.

萤火虫属于「完全变态」的虫，一生历经卵、幼虫、蜕皮、化蛹及羽化的过程。

ATP occurs wherever bacteria are present.Reaction of ATP with Luciferin Firetly in the presence of Luciferase results in the emission of light as a glow or flash.

ATP化验ATP和虫荧光素就是萤火虫当闪动的时候有细菌存在就有ATP存在。
