False.
They reproduce sexually, through eggs.
Metamorphosis is how some insect *develop* into adult.
Development into an adult is not the same as reproduction.

True. A small number of insects give birth to live young, but for most insects, life starts inside an egg. Insect eggs are protected by hard shells, and although they are tiny and inconspicuous, they are often laid in vast numbers. A female house fly, for example, may lay more than 1,000 eggs in a two-week period. As with all insects, only a small proportion of her young are likely to survive, but when conditions are unusually favorable, the proportion of survivors shoots up, and insect numbers can explode. In the 1870s, one of these population explosions produced the biggest mass of insects ever recorded: a swarm of locusts in Nebraska estimated to be over 10 trillion strong
