66-The Venus Flytrap混缩

66-The Venus flytrap

The Venus flytrap. Like the sundew, it makes itself very attractive, oozing nectar across the brim of each leaf. But any visiting insect had better watch out for these six tiny hairs.

This fly has to tread carefully. If it strikes one hair, it can carry on feeding but a timer has been set. A second strike in less than 20 seconds and the fly is doomed. An electrical impulse is triggered and the leaf snaps shut in just a fraction of a second. The tips lock together like prison bars. If the fly is very big or very small, it may just manage to escape. But most are trapped and die.

Ten days later, the trap reopens. All that remains is a husk. The plant has finished its meal and resets itself for its next victim.

捕蝇草

捕蝇草。像茅膏菜，它使自己非常有吸引力，在每个叶片的边缘都渗出蜜汁。但是任何来访的昆虫最好小心这六根细毛。

这只苍蝇要谨慎行事。如果它碰到一根捕蝇草的细毛，它还可以继续进食，但是计时器已经开启了。在20秒内，如果又碰到另一根细毛，这只苍蝇就会在劫难逃。一个电脉冲被触发，叶子眨眼之间就啪地一声闭上了。叶片尖端就像监狱的铁栅栏一样紧紧地锁在一起。如果苍蝇非常大或者非常小，它还有可能设法逃脱。但是大部分都被困其中并且命丧黄泉。

十天后，陷阱重开。里面只剩下了苍蝇的外壳。捕蝇草已经吃完了这顿饭，然后重设陷阱等待新的猎物。
