A waxy coating along the inside
All of the above
Nectar and pollen
An egg
To make a burrow to keep themselves cool in the summer
To find food underground
To make a nest for their young
To hide from birds that would eat them
They memorized a map
They hear them
They dig at random until they find one
They smell them

Most of the native bees in North America have already been studied.
Even native bees that can sting rarely sting people unless you scare or hurt them.
To find females to mate with
On flowers
In underground cells
In the bark of trees
In honeycombs
Do not be afraid of them
Be patient and observe them
Look for them places with many flowers
