The purpose of the Bug Blog is to provide information about and a forum for discussing the insects and other arthropods commonly encountered in Marin and Sonoma counties. Insect identification is a free service offered by the Marin/Sonoma Mosquito & Vector Control District. If you have an insect or arthropod that you would like identified, you may mail it to District headquarters or drop it off (in an enclosed container) at our front desk during regular office hours. Specimens will be identified as time permits.
