But soon this dry case bursts open, and out comes a full-grown fly.

但是很快, 这层干燥的硬壳就破开, 爬出来苍蝇的“成虫”。

When it's time to turn into an adult, they bury themselves deep underground.

当到了变成成虫的时候，把自己深埋在地下。

For one, it keeps larvae and adults from competing for the same habitats and food sources.

首先，这避免了幼虫和成虫争夺相同的栖息地和食物来源。

In fact, fireflies generally spend just a few weeks in their adult bodies and actually pass most of their lives as larvae.

事实上，萤火虫的成虫期通常只有几周，其生命周期主要以幼虫形态度过。

This lets adult and juvenile traits evolve independently from each other, since caterpillars and butterflies face totally different pressures for natural selection.

这使得成虫和幼虫的性状可以相互独立进化，因为毛虫和蝴蝶面临完全不同的自然选择压力。

You see, flies, as with most insects, undergo a complete metamorphosis from egg to adult via a larvae and a pupal stage.

苍蝇，和大数昆虫一样，经历幼虫和蛹的阶段，完成从卵到成虫的完全蜕变。

The locusts now transform into winged adults, and with conditions as good as this, they do so three times faster than normal.

蝗虫正在变态为有翅的成虫，由于生长环境良好，发育的速度达到平时的三倍。

Butterflies are just a few of the 800,000 insect species that transition from larvae to adults through complete metamorphosis.

蝴蝶仅是80万种通过完全变态从幼虫转变为成虫的昆虫之一。

If you eat infected raw fish, the larvae will mature into worms that can latch onto organs

如果你吃了受感染的生鱼， 这些幼虫发育成在器官上的成虫。

Over the following weeks, her larva hatches, bores into the cockroach, eats it alive, pupates in its carcass, and emerges as an iridescent adult.

在接下里的几周内，幼虫孵化，钻进蟑螂的躯体，活吃蟑螂，在的尸体中化蛹，再以成虫的形态闪亮登场。

A dense, smoky hand flew out of the tip of it and vanished—the ghost of the hand he had made worm-tail.

一只浓密的、烟雾缭绕的手从的尖端飞出，消失了——那只被他弄成虫尾巴的手的幽灵。

Estimating the PMI in this case relied on analyzing the life cycle of flies through development from egg to adult can be predicted based on environmental conditions.

在这种情况下，估计 PMI 依赖于分析果蝇从卵到成虫的生命周期，可以根据环境条件进行预测。

Insects hatch from eggs, and although some insects hatch as basically small versions of the adults of their species, others go through an incredible change before adulthood.

昆虫是由卵孵化而来的，虽然有些昆虫在孵化时，幼虫就是同类成虫的微缩板，但有些昆虫在成年之前发生翻天覆地的变化。

Previous efforts, they reckons, have been so focused on the dietary requirements of the carnivorous larvae that they have neglected those of the nectar-loving adults.

他认为，之前的努力过于专注于食肉幼虫的饮食需求，而忽视了喜爱花蜜的成虫的需求。

Previous efforts, they reckon, have been so focused on the dietary requirements of the carnivorous larvae that they have neglected those of the nectar-loving adults.

他认为，之前的努力过于专注于食肉幼虫的饮食需求，而忽视了喜爱花蜜的成虫的需求。

Although the team did not find tubeworm larvae, the adult worms they found beneath the crust were living in clusters of individuals of the same size, and therefore age.

尽管研究小组没有发现管虫幼虫，但他在地壳下发现的成虫都生活在大小相同、年龄也相同的个体群中。

Certain variations can only appear at corresponding ages; for instance, peculiarities in the caterpillar, cocoon, or imago states of the silk-moth; or, again, in the full-grown horns of cattle.

某些变异只出现在相应的年龄；例如，蚕蛾的毛虫、茧或成虫状态的特殊性； 或者，再一次，在牛的成熟角中。

And ants today are well-known for being eusocial insects—they have a division of labor, create colonies with multiple generations of adults, and many of the adults care for young that aren't their own.

今天的蚂蚁以其真社性而闻名——有劳动分工，建立包含代成虫的群体，并且许成虫照顾不是自己后代的幼虫。

What actually happens when a caterpillar morphs into a winged marvelous adult is so flippin' cool, some of nature's most remarkable biological processes and all of that mind blowing stuff happens in this part that the book just skips over.

当毛毛虫变成有翅膀的奇妙成虫时，实际发生的事情是如此酷，自然界一些最非凡的生物过程和所有令人兴奋的事情都发生在这一部分，这本书只是跳过了。

The unity of much of the morphogenesis of organisms from fertilized egg to adult began to be unraveled after the discovery of the homeobox genes, first in fruit flies, then in other insects and animals, including humans.

在同源盒基因的发现之后，从受精卵到成虫的生物体形态发生的一致性开始被解开。同源盒基因首先在果蝇中发现，然后在其他昆虫和动物中发现，包括人类。
