ground-nesting bee

6103  Hi. i found tons of these on my garden flowersbtoday on lac largille val des bois quebec. Not sure if its a green wasp. we have a wasp nest under the eavestrough. its new this spring. we have tons of bees as well. please help me id it.    thanks Sonja 

This is a solitary ground-nesting bee, but I cannot see the details needed to confidently say to which family it belongs. It most likely is a halictid (‘sweat bee’), but some megachilids (leaf-cutter bees) can be similar in appearance. In either case, it is a valuable pollinator that should be allowed to carry out its duties.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
