  • Or Osmia taurus. Unlikely to be distinguished from the photo.

  • Sam: There is a lot to consider here, and these issues will undoubtedly yield divergent opinions in this community but they are good ones to consider. I agree that not using effective sampling techniques to find where a disappearing species still exists, for fear of killing an individual, is counter-productive. We have no chance for conservation if we don’t know where species...

  • Hi Jessica and Eli: Megachile sculpturalis isn’t active until mid summer so it is unlikely they would be involved. When they are involved the carpenter bees end up on the ground below the nest partially covered in resin. I don’t have other ideas for the dead carpenter bees, though. It is not something I’ve seen around carpenter bee nest sites that I regularly see. T'ai On...

  • If you have to distinguish whether a bee foraged in Patch A, returned home, then flew to Patch B from whether a bee foraged in Patch A, returned home, flew back to Patch A, found nothing, then went to Patch B as Jim indicated originally then the only kind of strong data are likely to come from harmonic radar people, and I don’t think they have looked at solitary bees. Pollen...

  • Loriann: I typically mentor 1-2 undergraduates in research projects on bee biology/ecology each summer through NSF's Research Experiences for Undergraduates (REU) program at a field station (Blandy Experimental Farm) of the University of Virginia.

  • Russel: We see exactly the same thing on Digitalis grandiflora every summer at the State Arboretum of Virginia. Anthidium goes into the flower and drives out Bombus, which leaves the flower but usually doesn’t go very far away.

  • Sam: As far as I know, Augochlora pura only nests in soft wood, not the ground, which would lean toward Augochlorella unless it’s buried wood.

  • Nicholas: It sounds like an interesting study. I’m sure, however, that M. sculpturalis was in Georgia much earlier than 2011 given that it was reported from central Alabama, 30 miles or so from the Georgia border, in 2000. It was common in Auburn at that time. It might not be an easy publication to find, but it is Kondo T, Williams ML, Minckley R (2000) Giant...

  • Sam: I'm trying to give you the benefit of the doubt and see the merit of such a criterion, but I'm really struggling. When I give talks that include Peponapis I plot out its distribution and the approximate distribution of wild hosts in North America. Would it be oligolectic in those parts of the country where the are wild hosts and not oligolectic where there aren't? Seems a tad...

  • Doug: To follow Lisa's point. We caught 1 citrinus and 770 impatiens in passive traps across 17 sites. I don't have comparative trap data to talk about trends over time --only anecdotes. The data are just available for broader consideration of other sites and collections.
