En[t]omologist rehired – a Brief News Story
Aloha Daniel -
Thought you’d like to read over this brief news story about what budget crunches have done to our fragile eco system here. Sigh!
Happy Week ~

Banded Cucumber Beetle (from our archive)

Thanks for the information Eliza.  Rather than lamenting, we would be rejoicing that Hawaii has determined that an entomologist’s position had merit after all.  We are posting a photo of a Banded Cucumber Beetle from our archive to accompany your submission.

Invasive bug nabber back on the job
Entomologist position in county, lost in the budget cuts of 2009, has been restored; he is on the prowl again
April 9, 2012
By MELISSA TANJI – Staff Writer ( , The Maui News
KANAHA – Using a net, Mach Fukada swept over grasses and plants in a wetland area off a parking lot at Kanaha Beach Park last week.  He was looking for a green-and-yellow-colored insect called the banded cucumber beetle that he found by accident before he lost his job as Maui County’s state entomologist in 2009. He has since been rehired.”

Tortoise Beetle

Hi Markus,
You are correct that this is a Tortoise Beetle, and it is a nice addition to our website.  We have never heard of your location and upon doing some research, we now know that you are in Indonesia.

Hey Daniel,
thank you for your reply. I really love your webpage!
I think i spend hours today, watching the pictures.
Unfortunately i´m back home in germany since a week.

We are quite certain there are many interesting bugs in Germany.

Metallic rainbow beetle larvae in GA, USA wetland.
Location: Augusta, GA, USA

Hi, I found these larvae in large nests (clumps of dried leaves held together with webs) in a common shrub in an Augusta, GA wetland on February 11, 2012. I don’t know the name of the shrub, but I know it’s very widespread in wetlands in the southeastern USA. At any rate, these nests were very common throughout the shrubs, with several nests per shrub, and each nest seems to contain several larvae in various instars. The largest larvae I saw were ~1 cm long.

Hi Sarah,
WE are posting your photos as unidentified because we haven’t the time to research this at the moment.  Perhaps one of our readers will supply an answer in our absence.  The nest is quite a curiosity.  We wish you could supply the name of the plant.

Larval Nest

Comment from
That is the larva of Trirhabda bacharidis (Weber), a leaf beetle which is host specific to salt bush, Baccharis halimifolia. Don’t think it has anything to do with the “nests.”

It is interesting that the species name of the Leaf Beetle is derived from the generic name for the host plant.  We located this Coleopterists Bulletin article entitled “The Host Specificity and Biology of Trirhabda bacharidis“.  BugGuide calls it the Groundselbush Beetle.

Update from Sarah
March 31, 2011
I apologize for my tardy reply, but I believe the mystery is mostly solved.  I took the plant to a botanist and the bug to an entomologist at Georgia Southern University.  The botanist said the plant is Baccharis halimifolia, eastern baccharis.  The entomologist said he thinks the larvaea are Chrysomelid beetles, but he can’t identify them to species unless they’re grown out to adults.

ladybug’ish with stripes
Location: Houma, Louisiana, USA

I found this bug on my back door and I have never seen one like it before. We have warmer weather than usual so I thought maybe that is the reason for the unusual bug. It looked like a ladybug in shape and size, but its color was kind of reddish brown with gold stripes. Any ideas?

Leaf Beetle

Hi Karla,
We thought this resembled a Leaf Beetle in the genus
Calligrapha, and our suspicions proved correct when we matched your individual to images posted to BugGuide of Calligrapha (subgenus Bidensomela) bidenticola.

Leaf Beetle

Hi Bev,
This is not an Aphid, but rather, it is a Leaf Beetle in the family Chrysomelidae.  Though we were unable to identify the species, we did locate a similar photo from the Philippines on Project Noah.

Larger Elm Leaf Beetle

Dear Brian,
Using BugGuide, we properly identified your beetle as a Larger Elm Leaf Beetle,
Monocesta coryli.  Images posted to BugGuide indicate this is a variable species that may have black markings.
