What do mining bees look like?

Mining bees are 3/8 to 5/8 inch long.  They excavate tunnels in the ground just like miners, hence the name.  The entrance holes are typically small in diameter.  These holes often have a small mound of dirt resembling a small ant hill.  These furry bees range in color from dark brown, red to black, metallic green, to striped.

Life cycle of the mining bee

Complete Metamorphosis

These solitary bees live singly in burrows in the ground, however, large groups (aggregations) will sometimes live in same proximity due to the area being an ideal site to reside. 

Female mining bees collect pollen and nectar and stockpile it inside a burrow.  She then deposits an egg on the food source for the larva to feed on once it hatches. 

The larva will then pupate then emerging into the adult stage.  Overwintering occurs inside the burrows.  These bees are active for a minimal amount of time usually no longer than 1-2 weeks.

Female mining bees are capable of stinging, but typically only do so if provoked. As is the case with all bee stings, symptoms can be mild to severe. If you are stung by a bee and are experiencing trouble, you should contact your medical professional for advice. 

Helpful hints for mining bees

Mining bees are extremely beneficial and not necessarily a pest you want to discourage. If they are getting too close or you or a family member is allergic to bees, you can try to prevent them from taking up residence on your property by planting thick turf or ground cover as a deterrent. Treat your lawn or yard only if the infestation is severe or creating a hazardous situation.
