蝴蝶在雨中飞行时为什么翅膀不会被打湿 蝴蝶为什么不会被雨打湿英文双语对照

正确答案：翅膀上布满鳞片。

蝴蝶在雨中飞行时，它们的翅膀实际上会被打湿，但有几个原因使得它们能够继续飞行：

1、蝴蝶翅膀表面覆盖有一层细小的鳞片，这些鳞片像瓦片一样排列，具有疏水性，雨水很难粘附在上面，大部分会快速滑落。

2、蝴蝶的翅膀非常轻盈，即使沾了一些水滴，重量增加也非常有限，不会明显影响飞行能力。

3、蝴蝶扇动翅膀的频率很高，每秒可达几十次，这样能快速将翅膀上的水珠抖落。

4、蝴蝶的飞行肌肉很强健，足以克服翅膀沾水带来的阻力。

5、蝴蝶会本能地选择背风和避雨的飞行路线，尽量减少翅膀被打湿的程度。

蝴蝶翅膀的结构和特性以及飞行本领，使它们能够承受一定程度的雨水冲击，在小雨中继续飞行活动。但如果雨势太大，蝴蝶还是会选择停止飞行，找地方避雨的。

Right answer: Scale is bestrewed on wing.

Butterfly is in in rain when the flight, their wing can be hit actually wet, but a few reasons make they can continue to fly:

1, butterfly wing surface is enclothed have a petty scale, these scale are arranged like tile, have hydrophoby, water is very hard conglutinate above, major conference slides quickly.

2, the wing of butterfly is very lightsome, although touched a few water, weight increases very finite also, won't affect flight ability apparently.

3, the frequency of butterfly fan wing is very tall, every second can be amounted to a few times, the drip that can get on wing quickly so is shaken off.

4, the flight muscle of butterfly is very able-bodied, enough overcomes wing to touch the resistance that water brings.

5, butterfly can choose n and the flight route that take shelter from rain instinctively, reduce wing to be hit as far as possible wet degree.

The structure of butterfly wing and character and flight competence, it is certain to make they can bear the rainwater concussion of degree, in activity of flight of spit relay add. But if pluvial power is too great, butterfly or meeting optional stop flies, look for a place to take shelter from rain.
