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.”

Dear Bugman,
I would like to know the name of this bug I saw in the Cantabrian region (north of Spain) last week. I’ve searched through lots of websites and the only information I got is that it could be from the Chrysomelidae family.
I appreciate your help!

Plantain Leaf Beetle

Dear Claudia,
We tried, unsuccessfully, to identify this distinctive looking Leaf Beetle in the family Chrysomelidae.  Perhaps one of our readers will have better luck than we have had.

Thanks so much for your quick reply!
PS. I love your site
You are welcome, and thanks for the compliment. 

Plantain Leaf Beetle identification thanks to Karl
Hello Daniel and Claudia:
This distinctive beetle is Oedionychus cinctus (Family Chrysomelidae: Subfamily Galerucinae: Tribe Alticini). The common name appears to be Plantain Flee Beetle, and its distribution is Portugal, Spain and southern France.  Regards, Karl

Possible Beetle Larva and Description

Dear JW,
While we would very much like to provide you with a definitive identification for your 6 year old bug scientist daughter, the best we are able to provide is that this appears to be a Beetle larva.  There do not appear to be any visible wings present. We are curious why it is just a guess that it is eating leaves, and if so, what kind of leaves?  That might help with the identification.

I found this ladybug thing in my backyard in southern Louisiana in late Jan. The reason I say ladybug is its shape and wing structure. When it initially landed next to me it’s wings didn’t immediately tuck under its abdomen(?) after landing. I’ve searched the internet and can’t find a thing!

Leaf Beetle

Dear Buggy Fresh,
You have encountered a Leaf Beetle in the genus
Calligrapha.  According to BugGuide:  “38 spp. and sspp. in 4 subgenera in our area” and many species look quite similar, so we are reluctant to attempt a species identification.

Flea Beetle, we believe

Dear S. Frantz,
We believe this is some species of Flea Beetle in the tribe Alticini, a group in the Leaf Beetle family Chrysomelidae.  Your image resembles this image posted to iSpot.

Hello Daniel,
thank you very much for your detailed answer!!!!
It was a big help and I really appreciate your work.
Kind regards from Germany,

Spotted Cucumber Beetle

Dear CC,
We believe that if you look at images posted to BugGuide, you will agree that this is a Spotted Cucumber Beetle,
Diabrotica undecimpunctata.  BugGuide remarks:  “Considered a major pest of many field crops including cucumbers and other squashes, corn, soy. Beetles also transmit crop diseases such as bacterial wilt. Adults also reported damaging to garden plants including hibiscus, roses.”
