Blister Beetle

Found in Prince Edward Island, Canada
October 14, 2009
Hello! I was happy to find your site today! What a lot of wonderful and informative information!
Last summer on vacation, I snapped a nice photo of a most interesting flying insect. I still have no idea what it is. It was June and we were on Prince Edward Island, Canada.
There were many of these harmless and beautiful creatures flying among the lupines along the edge of the roads.
We enjoyed their magnificent beauty! I was so happy my not-so-great camera allowed me this beautiful shot of this fellow (or lady, as the case may be). They were about 2 inches long or so. Not tiny!
I would love to know what it is and what its habits are.
Thank you for all you’re doing!

Blister Beetle

Hi Linda,
This is a Blister Beetle, probably Lytta sayi.  You can find other photos and information on BugGuide.  Also, the entire family of Blister Beetles, Meloidae, includes members that are characterized by  the following BugGuide description:  “Pressing, rubbing, or squashing adult blister beetles may cause them to exude their hemolymph (‘blood’), which contains cantharidin. This compound causes blistering of the skin, thus the name blister beetle. Accidental or intentional ingestion of these insects can be fatal. There are documented incidents of horses dying after eating hay in which blister beetles were inadvertently baled with the forage. Watch that curious children do not attempt to put these beetles in their mouths. The external use of cantharidin, commercially known as ‘Spanish fly,’ the supposed aphrodisiac, is likewise discouraged.

Snail Eater

Big black beetle
October 13, 2009
Saw this big black beetle in September 2009 crawling in the leaf litter of the forest floor just north of Mendocino, California. It was approximately 1.75 inches long from the tip of its head to the rear of its carapace. When I discovered it and started taking photos, it didn’t scurry away; it slowly and methodically crawled away and hid under forest floor detritus.
Thanks for any help info you may have,

Snail Eater

This is some species of Snail Eater, a Ground Beetle in the genus Scaphinotus.  We don’t feel qualified to take the identification to the species level with the information provided on BugGuide, especially since some species are represented by a single photograph from California.  We might suggest that you also submit  your photo to bugGuide in the hopes that you can get a species identification.

Update from Eric Eaton
Daniel:
I’d need to see the specimen of the snail-eater to key it out to species….

Jewel Beetle from India

Hi Hari Iyer,
Yes, this is a Jewel Beetle, one of the common names for a Metallic Wood Boring Beetle in the family Buprestidae.  We will see if one of our readers is able to find the exact species name for you.

Ed Note: Thanks to Karl for providing a comment identifying the genus as Sternocera, and providing several links with confirmation imagery.

Goldsmith Beetle

Grapevine beetle?
October 9, 2009
This beauty was clinging to our screen door early one morning last June. I have been trying to identify, and Grapevine beetle seems a possibility (we have 17 acres of grapes), but there aren’t noticeable spots. What else could it be?

Goldsmith Beetle

Hi Charlee,
Your guess that this is a Grapevine Beetle is well founded, though incorrect.  This is a Goldsmith Beetle, Cotalpa lanigera, which is in the same tribe, Rutelini, as the Grapevine Beetle, Pelidnota punctata
.  You can see additional images and read more about the Goldsmith Beetle on BugGuide.  Our favorite bit of trivia about the Goldsmith Beetle, is that it is believed to be the Gold Bug in the famous Edgar Allen Poe story.

Thanks so much for the info! We have lots of unusual (for this area) bugs, birds, and varmints visiting our farm, and I was having trouble trying to identify this beetle. It certainly was beautiful– the same morning I photographed this guy, I also got great shots of a pair of Io moths. Living in the country certainly has its perks!
Thanks again,
Charlee

Hi Peter,
This is a Sexton Beetle in the genus Nicrophorus, possibly Nicrophorus orbicollis.  Sexton Beetles are sometimes called Burying Beetles.

Golden Beetle with Black Sanscript
October 3, 2009
Found in New England, near Boston MA: we saw one last year and this is the second one this year so far. Cannot find other pictures that look like it online. I realize it’s probably in the Eucalyptus family but no name that i could find.

Dogwood Calligrapha

Hi Leisu,
This is a Leaf Beetle in the genus Calligrapha.  We believe it is the Dogwood Calligrapha, Calligrapha philadelphica,
though there are several other species in the genus that could possibly be your beetle.  The eucalyptus family is a group of trees.  The family in this case is Chrysomelidae, the Leaf Beetles.  It is interesting that you noted the Sanscript since the genus name refers to the writing like markings on the elytra or wing covers.  BugGuide indicates that this species:  “Differs from C. multipunctata primarily in having the pronotum uniformly dark. Also, dark areas including spots are more likely to be dark metallic green in this species, in contrast with the black of C. multipunctata.

Mottled Tortoise Beetle from Mexico

Plastic Coated Beetle

I found this Beetle in August 2005 in Alamos Sonora, there are many unusual insects around at that time of the year because of the monsoon rains. This was the only time I ever saw this species. I’ve researched it a few times since but with no luck in finding out what it was.

Dear Mark,
We matched your photo to that of the Mottled Tortoise Beetle, Deloyala guttata, which is pictured on BugGuide.

Old Fashioned Potato Beetle Larvae

Yellow Caterpillars in Outfits
October 1, 2009
Size: about 3/4″
When: Oct 1, 2009, 9:45AM
Where: Underside of native Jimsonweed leaves, on a large sunny meadow off Riverside Drive.
I’d been hoping to find Hawk Moth caterpillars since there was such a huge patch of Jimsonweed. Most of the plants had only tiny bites taken out of them. The plants that had the largest bites had these fat little caterpillars with what looks like bird excrement hanging off their backs. Great camouflage!
Also intersting – the chewed edges of the leaves are blackened, appearing as if they had been burned. (See photo) The plants with tiny bites had no black marks like these.

Old Fashioned Potato Beetle Larvae

Hi Diane,
If it looks like a caterpillar and acts like a caterpillar, it is not necessarily a caterpillar.  Many beetle larvae and sawfly larvae are confused with caterpillars.  These are not caterpillars.  They are beetle larvae, and more specifically, they are Old Fashioned Potato Beetle Larvae, Lema daturaphila, also called Three-Lined Potato Beetles.  According to BugGuide, the scientific name “Means ‘Datura loving.’ Datura is a genus of plant in the Nightshade family. The potato is not in the genus Datura, but is in the Nightshade family. This beetle feeds on both potato plants and other members of the Nightshade family.”  We noticed that you have the embedded location information as the 18 acre parcel on Riverside Drive.  We know that land, but never knew it was part of Elysian Park.  We have a certain fondness for Elysian Park.  That is where we found our cat as a stray kitten 11 years ago, and he is just the sweetest cat ever.

Daniel,
Thank you!    I’ll credit What’s that bug? (with a link) for the ID.  I’ll be posting a similar photo on my blog http://redcarproperty.blogspot.com/ probably Monday.  Feel free to use the photo I sent you as long as my photo credit is on it.  No wonder I couldn’t find it under caterpillars.
By the way, that part of Elysian Park is undergoing environmental review for park improvements, see: http://www.theeastsiderla.com/2009/10/do-you-want-park-or-parking-lot.html
