Life cycle of the leafcutter bee

Complete Metamorphosis

Leafcutters are solitary bees where the female takes care of all the work unlike the behavior of colony bees that are assigned a role per caste.  The female lays 35-40 eggs at a time inside nests created from leaves.  They are filled with nectar and pollen for the larva to feed once hatched.  Pupation occurs over the winter with the adults beginning to emerge in spring and living up to two months.

Are leafcutter bees dangerous?

Bee stings can produce a variety of reactions ranging from temporary pain and discomfort to severe allergic reaction. 

Where do leafcutter bees nest?

Leafcutter bees like to "cavity nest". That means they prefer to establish their nests in ready-made cavities. They also create nests in soft rotting wood that can be excavated.

‟I bought a home, sight unseen (I trusted a VA inspector) in rural Cochise County, AZ.
After moving in I quickly discovered that the home was INFESTED with vermin and BROWN RECLUSE SPIDERS!

NW Exterminating installed ‘Desert Guard’ and that took care of ALL of the vermin, and, after a few treatments of Spider Power-Dusting in my crawl space I am free of dangerous spiders!
