Even native bees that can sting rarely sting people unless you scare or hurt them.
All of the above
To make a nest for their young
To find food underground
To find females to mate with
Most of the native bees in North America have already been studied.
They smell them
They memorized a map
They hear them
They dig at random until they find one
In underground cells
In honeycombs
On flowers
In the bark of trees

Nectar and pollen
An egg
A waxy coating along the inside
Do not be afraid of them
Be patient and observe them
Look for them places with many flowers
To hide from birds that would eat them
To make a burrow to keep themselves cool in the summer
