It takes about 7-10 days for an egg to develop into an adult mosquito.

虫卵发育成成虫大概需要7-10天。

Life stages of Aedes aegypti and Aedes albopictus mosquitoes

埃及伊蚊和白纹伊蚊的生活史

Eggs 

卵

••Adult, female mosquitoes lay eggs on the inner, wet walls of containers with water, above the waterline.

••Eggs stick to container walls like glue. They can survive drying out for up to 8 months. Mosquito eggs can even survive a winter in the southern United States.

••Mosquitoes only need a small amount of water to lay eggs. Bowls, cups, fountains, tires, barrels, vases, and any other container storing water make a great “nursery.”

虫卵看起来像黑色的泥块。

••雌性成蚊在盛水容器内壁的水平线上产卵。

••卵像胶水一样粘在容器壁上。它们在干燥环境下可以存活长达8个月。在美国南部地区，蚊卵甚至可以存活过冬。

••蚊子只需要很少量的水就可产卵。碗、杯、喷泉、轮胎、桶、花瓶以及任何可以存储水的容器，都是很好的“温床”。

Larva 

幼虫

••Larvae live in the water. They emerge from mosquito eggs. This happens when water (from rain or a sprinkler) covers the eggs.

••Larvae can be seen in the water. They are very active and are often called “wigglers.”

水中的幼虫（孑孓）。

••幼虫在水中生活。它们由卵孵化而成。只要有水（雨水或喷洒的水）覆盖虫卵时就可孵化。

••幼虫在水中可见。它们非常活跃，常被称为“孑孓”。

Pupa

蛹

••Pupae live in the water. An adult mosquito emerges fromthe pupa and flies away.

••蛹在水中生活。蛹孵化成成蚊后飞走。

Adult 

成虫 

• Adult female mosquitoes bite people and animals.Mosquitoes need blood to produce eggs.

•• After feeding, female mosquitoes look for water sources tolay eggs.

•• Aedes aegypti and Aedes albopictus don’t fly long distances.In its lifetime, a mosquito will only fly within a few blocks.

•• Aedes aegypti mosquitoes prefer to live near and bitepeople.

•• Because Aedes albopictus bite people and animals, they canlive near homes or in neighboring woods.

•• Mosquitoes live inside and outside.

成蚊在叮咬人。

••雌性成蚊叮咬人和动物。蚊子需要吸血才可产卵。

••吸血后，雌蚊寻找水源产卵。

••埃及伊蚊和白纹伊蚊飞得并不远。一生中，蚊子只会在几个街道内飞行。

••埃及伊蚊喜欢住在人类附近，叮咬人。

••由于埃及伊蚊要叮咬人和动物，它们会在住家附近或邻近的树林中生活。

••蚊子在室内和室外生活。
