I saw this beetle on a citrus shrub in my yard last month in West Los Angeles in the Santa Monica Mountains. It’s about the size of a Ladybird Beetle.

Australian Tortoise Beetle

Hi Robert,
According to BugGuide, the Australian Tortoise Beetle or Eucalyptus Tortoise Beetle,
Trachymela sloanei, was:  “Introduced from Australia. First recorded in 1998 in California.”  BugGuide also indicates that it feeds on Eucalyptus, and there is no indication it feeds on citrus.  The County of Los Angeles Agricultural Commissioner has an excellent pdf on this “new agricultural pest for Southern California.

Thank you so much for the ID on this beetle. It just so happens that we have two huge Eucalyptus trees in our yard. Somehow he found his way to the citrus.
Thanks again.
