This large weevil (over 1/2″) gave itself away as it flew around the garden, possibly in search of its host plant Hesperoyucca whipplei, or Chaparral Yucca. Adults of this weevil species are usually out seeking mates between March and July, but with the unseasonal warm stretch of weather we’ve had it, along with other insects, has become active earlier than normal.
