“Pupa”是昆虫生命周期中的一个关键阶段，具体解释如下：
“Pupa”（复数形式为pupae）指昆虫从幼虫发育为成虫的中间蛹态阶段。此时昆虫处于非活跃状态，不进食，体内发生完全变态（如蝴蝶、蛾类等）。该阶段介于幼虫（larva）和成虫（adult）之间。
单词源自拉丁语pupa，原意为“女孩”或“玩偶”。18世纪由生物学家林奈（Linnaeus）引入，用以描述昆虫发育中看似静止但内部剧烈变化的阶段。
不同昆虫的蛹可能有不同形态，如蝶类的蛹常包裹在茧（cocoon）中，而甲虫的蛹则裸露（pupa exarata）。如需更详细分类，可参考昆虫学专业文献。
Pupa是一个名词，指的是昆虫的蛹。下面是对该词的详细解释：

The pupa stage is a critical time in the life cycle of insects. (蛹期是昆虫生命周期中一个关键的时期。)

Chrysalis (蛹壳)
Cocoon (茧)
Larva (幼虫)
Adult (成虫)
The scientist carefully observed the pupa of the beetle under the microscope. (科学家在显微镜下仔细观察了甲虫的蛹。)
After spinning a cocoon, the silkworm will enter the pupa stage. (吐丝茧后，家蚕会进入蛹期。)
