An egg
All of the above
A waxy coating along the inside
Nectar and pollen

In underground cells
In the bark of trees
On flowers
In honeycombs

To find food underground
To make a burrow to keep themselves cool in the summer
To hide from birds that would eat them
Even native bees that can sting rarely sting people unless you scare or hurt them.
To find females to mate with
Most of the native bees in North America have already been studied.
