"Dear Bay Area invasive species stakeholders,
A UC IPM colleague just (belatedly) informed me of a sighting in January of the invasive bagrada bug in San Francisco:

Prior to this confirmed (photo positively identified) sighting, the bugs had not been seen north of the Monterey area. This insect may represent a serious new pest for San Mateo County's Brussels sprouts and cole crops growers (preferred hosts are in Brassicaceae), a nuisance pest for urban gardeners (often found associated with sweet alyssum), and a new nuisance pest for structural pest control operators (aggregates and seeks shelter in structures in late autumn). I will try to contact the resident who took these photos so that San Francisco's Agriculture Department can investigate further if desired.
Happy Friday to all,
Andrew
