Why do insects lay so many eggs?
Animals have two ways to make sure that they leave offspring in
the world, so that their genes survive. One is to have few children and care
for each one intensely (humans do that). The other is to have huge numbers of
offspring, so that even though many die enough survive. That is what insects
do. Most of those eggs, or the larvae they give birth to, will die in one way
or another, so there have to be many of them.
