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