Subject:  Eucalyptus Leaf Beetles found in Mount Washington
Location:  Mount Washington, Los Angeles, California
April 25, 2017
About two weeks ago, we were walking down the street and we noticed that something was chewing the leaves of a big eucalyptus tree growing on the side of the road.  Sure enough, we found Eucalyptus Leaf Beetles,
Paropsisterna m-fuscum, including one larva.  When we returned to take some images, we could not locate the larva.  According to BugGuide:  “native to Australia, introduced into so. CA (ca. 2003).”  According to iNaturalist:  “This insect can become very prolific and is a serious pest species in the forestry industry. This particular species is a problem on Blue Gum in California, USA.  The beetles are pale, with variable brown markings on the elytra and pronotum and sometimes with bright flaring at the base of the elytra. The larvae are larviform and pale green like the leaves they eat.”

Good Afternoon Bugman,
I did some research to see if I could see what kind of bug my kitty brought me to show his catch. I do not know which part of the house he retrieved this bug from.
I was unsuccessful in finding the answer, but the similarities are between a kissing beetle and a soldier beetle ? Can you help me ?
Thank you have a nice day !!

Found this guy on my porch. Never seen anything quite like it in this part of Southern California. I’m currently working on a few non local bonsai and was thinking he came along for the ride. Any info would help. Thanks.

Dear Jay,
This is certainly an Ant, and it resembles the invasive, exotic Argentine Ant.  Here is a BugGuide image of Argentine Ants.  We find it really hard to believe that anyone living in Southern California, especially someone who works with plants outdoors, has never seen Argentine Ants.  How large is it?  Was it alone?

Dear Coty,
This is not a Worm.  It is a Millipede, possibly a Greenhouse Millipede,
Oxidus gracilis, and according to BugGuide: “Native to Asia, introduced to North America and found throughout the lower 48 states and southern Canada.”  The problem is most likely with the landscaping as this is not an aquatic species.  It is falling into the pool, not living there.

What would be a good insecticide to help knock them down? I keep all the flower beds and grass around it as clean as possible.

We do not provide extermination advice.

We just recently moved into our new place and found these bugs crawling into our living room from the patio door and molting They moved very slow and when i try to catch one, it jumped up about 12 to 18 inches straight up. I lived in Southern California and never seen an insect like this. Can you help me identify this insect, thank you.

Lawn Shrimp

Dear Jonathan,
Commonly called a Lawn Shrimp or House Hopper, this terrestrial Amphipod is not an insect, but a Crustacean.  Lawn Shrimp are native to Australia, but they have naturalized in Southern California because of the irrigated gardens that are so common.

Thank you for identifying the critter.  My son was so excited when I read the email you had sent and how amazed he was how a shrimp can live in our yard.  Thank you and we will be visiting the site to identify all the insects and non insects we find in our backyard and vegetable garden.   I found your site to be very educational and entertaining, thank you!
Best Regards,
Jonathan Kim

A large number of these pinhead sized bugs hatched on my bonsai maple buds and leaves on a warm February week.

Maple Aphid, we believe

This is an Aphid, and based on our research and information contained on Influential Points and BugGuide, we suspect this is a Maple Aphid, Periphyllus testudinaceus, a species native to Europe. 

Thanks Daniel,
This is great information and very interesting.
