All of the above
Do not be afraid of them
Look for them places with many flowers
Be patient and observe them
They smell them
They hear them
They dig at random until they find one
They memorized a map
Most of the native bees in North America have already been studied.
An egg
Nectar and pollen
A waxy coating along the inside
To hide from birds that would eat them
To make a nest for their young
To find food underground
To make a burrow to keep themselves cool in the summer
To find females to mate with
In honeycombs
In underground cells
On flowers
In the bark of trees
