Hi Mr. Marlos,
I’m an entomologist living in the San Francisco Bay Area and I just wanted to drop you a line to let you know that I have found Phyllodromica trivittata in Vallejo in Solano County and that it probably came in on wood a friend brought me from Walnut Creek in Contra Costa County. It appears our friend is spreading quite quickly.
