Metallic rainbow beetle larvae in GA, USA wetland.
Location: Augusta, GA, USA
February 17, 2012 7:04 pm
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.
Thanks!

Larva

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

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

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.

Spotted Cucumber Beetle

Dear Brian,
Though it superficially resembles a ladybug, this is actually a Spotted Cucumber Beetle,
Diabrotica undecimpunctata, and you may verify that on BugGuide.

Lady beetle – near Toronto ON
Location: King City (north of Toronto)
October 24, 2011 8:15 am
Hello…
The attached lady beetle was found in a forested area about 30 km north of Toronto. Note the unusual marking and, even more, the embossed textured lines running parallel to the centre. Would this be another weird variant of the Asian multicoloured?
Date was May 19, 2011.
thanks!

Leaf Beetle: Calligrapha rowena

Hi Gavin,
Your beetle is not one of the Lady Beetles despite the black and orange coloration and the small size.  This is actually a Leaf Beetle, and we followed our first suspicion that it is in the genus
Calligrapha, and we quickly identified it as Calligrapha rowena, which has no common name.  According to BugGuide, it feeds “on Cornus (dogwood).”  The leaf in your photo appears to be a dogwood leaf.

Leaf Beetle: Calligrapha rowena

Hello Daniel:
Thanks very much for your quick reply! This makes a lot of sense, given the dogwood the beetle was on (and abundant in the area). And the patterning on the wing cases is indeed calligraphic.
cheers,
Gavin
