The Bug Blog

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 (attn: Eric Engh) or drop it off (in an enclosed container) at our front desk during regular office hours. Specimens will be identified as time permits.
