Little and large. Bugs are insects, spiders, and other creepy- crawlies. They come in all shapes and sizes. This is an African goliath beetle. It is the biggest and heaviest bug in the world. The photo shows the beetle's real size.

大大小小的。虫子是昆虫、蜘蛛和其他令人毛骨悚然的爬行动物。 它们有各种形状和大小。 这是一只非洲巨人甲虫。 它是世界上最大最重的虫子。 这张照片显示了甲虫的真实尺寸。

Bug bodies. Bugs can look very different, but they have some things that are the same. They don't have bones. Instead, they have a hard shell on the outside of their bodies. The shell is called an exoskeleton. This rhinoceros beetle has a very strong exoskeleton.

虫子尸体。虫子可能看起来很不一样，但它们有一些东西是相同的。 它们没有骨头。相反，它们的身体外面有一层硬壳。 这种外壳被称为外骨骼。 这种犀牛甲虫有非常强壮的外骨骼。

Bugs have at least six legs. Some, such as millipedes, have many many more. Bugs' bodies are made of segments joined together. Wasps have three main parts. Head Thorax Abdomen Flies have sticky feet so they can walk upside down.

虫子至少有六条腿。 有些动物，比如千足虫，有很多很多。 虫子的身体是由连接在一起的部分组成的。 黄蜂有三个主要部分。 苍蝇的脚很粘，所以它们可以倒着走路。

Baby bugs. Most baby bugs hatch from eggs. A mother spider lays lots of eggs. Inside each one is a baby spider. She makes silk and wraps it around all the eggs to make an egg sac. She attaches the egg sac to her body and carries it around with her. The baby spiders grow bigger inside the eggs. Then they hatch out.

婴儿bug。大多数臭虫是从卵中孵化出来的。 蜘蛛妈妈产很多卵。 每个里面都有一只小蜘蛛。 她用丝把所有的卵包裹起来做成卵囊。 她把卵囊粘在身上，随身携带。 小蜘蛛在卵里越长越大。 然后孵化出来。

These baby shield bugs are called nymphs. Their mother is protecting them from a hungry spider. A mother cockroach can have as many as two million babies a year!

这些小盾虫被称为若虫。 它们的妈妈正在保护它们不受一只饥饿蜘蛛的伤害。 一只蟑螂妈妈一年可以生多达200万个宝宝！
