The California Native Plant Society (CNPS) invites the public to "Updated research into gall wasps (Cynipidae) in Northern California," by Dr. John DeMartini, Humboldt State University Professor emeritus, Wednesday, February 12, 2020, at 7:30 p.m. at Six Rivers Masonic Lodge, 251 Bayside Road, near 7th and Union in Arcata. The tiny gentle wasps of the family Cynipidae produce galls on roses, thimbleberry, oaks, tan oak, and chinquapin. In a presentation six years ago, Dr. DeMartini only covered oaks, but this evening he will add new findings about the life histories of these wasps on other woody plants. Doors open at 7:00 p.m. for snacks, sales, and socializing. The North Coast Chapter of CNPS offers free public programs on the second Wednesday of each month, September through May. 707-822-2015, www.northcoastcnps.org.
