I gave a Zoom lecture last night on why people should care about native bees, and promised the audience (friends of Belmont Hills Library, in Bala Cynwyd, PA) that I’d share some links, photographs, and answers to some of the questions at the end. If you have any lingering questions or thoughts, please don’t hesitate to contact me. Good luck attracting bees, and thanks again for the invitation.

Answers to questions

Good native ground cover to replace English ivy? A: golden groundsel (Packera aurea).
Honey from any native bees? A: yes, from stingless bees. I have a few photographs from Costa Rica and Mexico. It’s more liquidy than European honey bee honey.
Are yellow jackets wasps or bees? A: wasps
How deep do ground-nesting bees dig? A: I looked up the record and in some species the tunnels can extend down 10 feet or more. But 12 to 18″ is more typical.
Do figs actually eat wasps? A: Figs in the wild are pollinated by wasps, but as I mentioned, the varieties we grow in the United States don’t require pollination, so the crunch is not due to wasps within. Fig and biology fans should read Gods, Wasps, and Stranglers: the Secret History and Redemptive Future of Fig Trees.
Is it worth keeping hostas in pots for leafcutter bees A: It is never worth keeping hostas alive for any reason. But leafcutter bees will use them, I’ve read.
