The bones and bugs are back, and so are the flowers and fish. But this year’s UC Davis Biodiversity Museum Day, Saturday (Feb. 13), will welcome even more diversity: nematodes and raptors, the arboretum and Häagen-Dazs Honey Bee Haven — and even yeast!

In the event’s fifth year, the additions bring to 11 the number of research collections that the public is invited to see. The collections showcase natural history, biodiversity and the cultural-ecological interface.

Admission and parking are free. The earliest open house begins at 9 a.m. and the latest closing time is 4 p.m.

Here’s the schedule:

• Anthropology Museum — noon-4 p.m.
• Arboretum and Public Garden — 10 a.m.-4 p.m.
