Come into my parlor1, said the spider to the fly.

近来吧,到我的客厅来,蜘蛛对苍蝇说道。

At least that's usually the way it goes. In most showdowns between spiders and flies, the odds2 weigh heavily in the spider's favor. Today, however, we'll look at a few species of fly that manage to turn the tables on their eight legged foes3.

至少这种情形经常发生。在蜘蛛与苍蝇的较量中,蜘蛛的胜算占多数。今天,我们将会观察几种苍蝇,看它们是如何成功反击,打败那八条腿的敌人?

When many spiders capture a fly, they don't eat it right away. Instead, they poison the fly and wrap it in silk. They leave this silk-wrapped package for later consumption, just the way you store food in your pantry instead of eating it all right there at the supermarket.

许多蜘蛛捕获到一只苍蝇时,并不立即把它吃掉。相反它们会给苍蝇注射毒液,吐出蛛丝将其团团围住。它们留着苍蝇包裹晚点再享用。正如你逛完超市后把食品储存在食品柜里,而不是立刻就吃掉一样。

Imagine yourself as a fly passing a web full of these wrapped-up dead flies. You might imagine you'd be frightened by the spectacle of your comrades, wrapped up like so many Hostess Twinkies. Not so for the Microphorus crassipes. This fly species sees a spider's larder4 as a golden opportunity. Indeed, it gets most of its food by stealing these silk-wrapped packages--very carefully of course--from spiders.

假想自己是一只苍蝇,正飞过挂满这种死苍蝇包裹的蛛网。你也许会被同伴们壮烈的惨象吓到。但是对Microphorus crassipes而言,却并不会如此。这种苍蝇视蜘蛛的储物柜为绝好的机会。确实,它通过偷取这些包裹来获取大部分食物,当然它也会十分小心地提防蜘蛛。

Another type of fly found worldwide, called Robber Flies, take this thieving concept one step further. Instead of just stealing the spider's food, certain robber flies go after the spider itself. Robber flies have been seen snatching a spider off of the ground, carrying it away, and eating it.

世界上另一种苍蝇——食虫虻,更进一步地发扬了这种偷盗概念。它不仅偷取蛛网上的食物,还跟踪蜘蛛。有人见过食虫虻将蜘蛛打翻在地,将其拖走食之。

Even worse news for spiders: There's a whole family of flies--the Small Headed flies--whose larvae5 actually develop inside a spider's body. These fly larvae burrow6 into a passing spider, then proceed to eat the spider from the inside out. Spider or fly, fly or spider. Betting on the spider isn't always a sure thing.

还有更令人发指的消息:有一种小头苍蝇,它们整个家族的幼虫都是在蜘蛛体内发育成熟的。这种幼虫趁蜘蛛走过时钻入其体内,接着就一点点由内到外吃掉蜘蛛。蜘蛛还是苍蝇,苍蝇还是蜘蛛,赌蜘蛛赢也不见得总是对的。
