Look for them places with many flowers
All of the above
Do not be afraid of them
Be patient and observe them
They dig at random until they find one
They hear them
They memorized a map
They smell them
A waxy coating along the inside
An egg
Nectar and pollen

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