6623. This bug was in a dead oak that died last year…. can you please identify it for us. My husband cut it up last year and we just pulled it out of the bush…. a few of our oaks have died this year and last year. We found the bugs this week Aug 26 2019. We think they are emerald ash borer…do they act the oaks too? Mooretown, ON. Canada
Number 6623. This is a solitary ground-nesting bee in the family Halictidae. Some species in this family are called sweat bees as they seem attracted to human perspiration; all are valuable pollinators.
