Yellow Star Thistle Hairy Weevil
Yellow Star Thistle Hairy Weevil
Eustenopus villosus

There are many weevils here at Kaweah Oaks Preserve, but pictured above is the newest and possibly the most welcomed one ever to be introduced in California. This insect is the biological control for the noxious weed, the yellow star thistle. Dennis Haines with the Ag Dept., our resident expert on insects and plants in Tulare County, has released 200 adult weevils on a two acre patch of star thistle near the Swamp Trail. He is going to monitor how much control these weevils will have over the next few years. We all hope this procedure will help eradicate the dreaded yellow star thistle from the Central Valley.
