课文

Fireflies produce light through bioluminescence — a chemical reaction inside living tissue that releases energy as visible light.

萤火虫通过生物发光产生光——即活体组织内释放可见光的化学反应。
The key chemicals are luciferin, oxygen, and the enzyme luciferase, which together create cold, efficient light without heat.

关键物质是荧光素、氧气和荧光素酶，三者协同产生冷光，高效且不产热。
Each species has its own genetically programmed flash pattern, including duration, interval, and number of pulses.

每种萤火虫都有由基因决定的独特闪光模式，包括闪光时长、间隔和脉冲次数。
Neural signals trigger bursts of oxygen delivery to light-producing cells, allowing precise timing down to milliseconds.

神经信号触发氧气脉冲式输送至发光细胞，实现毫秒级精准控光。
Males flash while flying to attract females, who respond with species-specific delays — like a coded conversation in darkness.

雄虫飞行时闪光以吸引雌虫，后者则以物种特异的延迟回应——宛如黑暗中的密码对话。
Some predatory fireflies even mimic these patterns to lure and eat other species, showing how vital timing is for survival.

一些捕食性萤火虫甚至模仿这些模式诱捕并吞食其他种类，凸显精确时序对生存的关键作用。
Temperature also affects flash rate: cooler nights slow metabolism, making flashes slower and longer.

温度也影响闪光频率：凉爽夜晚会降低新陈代谢，使闪光变慢、变长。
Scientists study these rhythms to understand circadian control in insects and develop new bioimaging tools.

科学家研究这些节律，以理解昆虫的昼夜调控机制，并开发新型生物成像工具。
