Found a few of these crawling around a small shrub at the edge of the woods behind my house; North Carolina, Croatan Forest, Longleaf Pine/swamp habitat. Never seen colors like this before and can’t find it in my caterpillar book nor online. (You try Googling rainbow caterpillar/larvae and see what you get! LOL . . .)
Help?

Groundselbush Beetle Larva

Groundselbush Beetle Larva

Dear Diane,
We have trouble remembering the name of the Groundselbush Beetle Larva,
Trirhabda bacharidis, but we always remember its distinctive appearance and we can quickly locate older postings of Groundselbush Beetle Larvae.

Hello Daniel,
thank you and you are right after searching for the name.
Here is something that might interest you:
This is an “orchid lover” … a real pest at orchid nurseries here in Thailand.
People call it “Pumpkin beetle” (Aulacophora abdominalis) but it isn’t one. Look at black legs and antennae.
And it’s neither Stethopachys formosa or Lema pectoralis, but close to them.
The bug and its larvae love orchid flowers, especially these of the Aeridinae group (Vanda, Rhynchostylis, Seidenfadenia and all of their hybrids), Dendrobium and Spathoglottis.
Regards … Ricci

Hi Ricci,
In the future, please submit new requests by using our standard submission form.  We realize it is easier for you to just attach additional images to a previous response, but it makes our postings so much easier if we are able to use the format of our submission form.  Thanks so much for sending us images of two phases of this Leaf Beetle.  We haven’t the time to research its identity this morning, but we are posting the images and we will provide additional feedback at a later time.
  We hope the eggs are not exported with the orchids because the introduction of a major orchid pest can wreak havoc on orchid nurseries around the globe as orchids are such a popular gift item.

Update:  March 4, 2015
We did locate this similar search for an identification on the Dokmai Dogma Drama In The Orchid Nursery posting.

Hi Daniel,
the orchid nurseries that export their plants use so much poison (most of it is forbidden in Europe) … no egg or Beetle will survive this.
When I asked a friend who own a nursery about this beetle, she answered:
“For bug (Pumpkin beetle) use Dicrotophos and Sticking Agent spray 5 days per time. And larva use Abamectin and Sticking Agent.”
Abamectin and Dicrotophos are highly toxic and dangerous for the environment.
Btw.:
– In Australia the black and yellow Dendrobium beetle (Stethopachys formosa) is a pest in orchid nurseries.
– Lema pectoralis has been reported from orchid nurseries in Thailand.

Hello, I’m a gardener living in the south of England. I saw these beetles living on a rosemary bush. There was about 15-20 of them. I saw the over two seasons on the same rosemary bush but never anywhere else in the garden or in England for that matter.
Any ideas?

Rosemary Leaf Beetle

Rosemary Leaf Beetle

Dear Jackson,
You have the hands of a gardener.  Your beetle is a Rosemary Leaf Beetle,
Chrysolina americana, which is sometimes called merely a Rosemary Beetle.  Knowing that it feeds on a single plant in your garden, Rosemary, is a good way to search for its identity.  According to UK Safari:  “Despite the scientific name, this beetle is a native of southern Europe.  It was first noticed in the U.K. in the early 1990’s and has since become well established.”  You can locate additional information on the Royal Horticultural Society website where it states:  “The larvae and adults feed on the foliage of rosemary and related plants.  Rosemary beetle is a pest that eats the foliage and flowers of various aromatic plants, such as rosemary, lavender, sage and thyme.  Initially rosemary beetle was found mainly in London gardens, but it is rapidly spreading and is becoming widespread throughout England and Wales, and possibly further north.”

Hello again! I found this lovely iridescent beetle this morning, sitting on a leaf near one of our tiny seasonal creeks. It looks something like Chrysochus auratus, but the references I see for that species say it is found in Northeastern US, and I am in the Sierra Foothills of California (oak savannah terrain). Can you help me identify this one?

Possibly Leaf Beetle

Possibly Leaf Beetle

Dear Megan,
This is not a Dogbane Leaf Beetle, but we believe your metallic beetle is also a member of the Leaf Beetle family Chrysomelidae.  At this time, our research has not produced a visual match.

Leafminer Beetle

Lantana Leafminer Beetle

Dear David,
This sure looks to us like a Leafminer Beetle in the family Chrysomelidae, probably a Lantana Leafminer Beetle,
Octotoma scabripennis, which we found pictured on the Brisbane Insect Website where it states:  “Lantana Leafminer Beetles are easily found on Lantana. Their larvae mine in the middle layers of leaves and pupate there. The adult beetles feed on the leaf surface. “  We also learned:  “Lantana Leafminer Beetles are introduced to Australia as a biological control to the weed Lantana Lantana camara.  The beetle’s feeding activities reduce plant vigour and suppress flowering.”  The Department of Agriculture, Fisheries and Forestry Biosecurity Queensland site has an excellent Fact Sheet on the Lantana Leafminer Beetle where we learned:  ”  Octotoma scabripennis occurs naturally from Mexico to Nicaragua.  Cultures of Octotoma scabripennis originated from Mexico.  The insect was first released in Australia in 1966.”  The Lantana Leafminer Beetle is also pictured on the American Insects site.

Leaf Beetle Larva

Leaf Beetle Larva

Dear Dylan,
We received your submission with three unrelated insects attached to a single, very brief identification request.  Before we could even begin, we needed to research the location of “brisdane moggil” which we quickly learned was a spelling error of Brisbane Moggil, an area in Queensland Australia.  We try to the best of our ability to classify postings correctly on our site and information on the sighting is often very helpful.  With that stated, one of your images is of a Leaf Beetle Larva.  If you want any additional identifications, please submit a single individual, but you may attach as many as three images of that individual as sometimes multiple views assist in our identification process.  Please include any relevant anecdotal information regarding the sighting.
