I found a really pretty green beetle on campus today. Some mean boys were throwing it, and I thought it was dead, but when I picked it up it moved a little bit! I’d like to know what kind of bug it is, so I can maybe save it, and if not, maybe I’ll keep it.
Can you help me?

Dear Mrs. London,
This gorgeous Scarab Beetle is a Shining Leaf Chafer in the subfamily Rutelinae that does not have a distinct common name, and its scientific name, Paracotalpa puncticollis, is quite a mouthful.  It is pictured on BugGuide, but there is not much additional information.  According to the Coleopterists Bulletin:  “Paracotalpa puncticollis is usually found in pinyon-juniper areas, and appears to be associated with plats of the genus Juniperus.  Observations of adults emerging from litter at the base of juniper may indicate that larvae feed on roots of this plant.  Adults have been observed feeding on needles of juniper, and analysis of fecal material has confirmed this adult diet.”  Because of your kindness, we are tagging your submission with the Bug Humanitarian Award.

How you want your letter signed:  Anyway you like

We quickly identified your Leaf Chafer as Paracotalpa granicollis thanks to this BugGuide image.  According to BugGuide:  “Has been associated with Juniperus species, which is likely an adult food plant.” 

Letter 3 – Oriental Beetle

Similar to Japanese Beetle in Size

This beetle is seen in my garden. It is similar in size to the Japanese beetle. I found this beetle on a grape leaf. It is mid-July and I have been seeing them for about a week.
Cathy
Nothern Westchester County, New York.

Hi Cathy,
Your beetle is a Shining Leaf Chafer in the same subfamily as the Japanese Beetle.  We believe it is in the genus Strigoderma based on images posted to BugGuide. Perhaps one of our readers can verify this.

Correction from Eric Eaton
Daniel:
The “shining leaf chafer” you thought might be Strigoderma is actually the “Oriental beetle,” Anomala orientalis, incredibly abundant right now here in western Massachusetts….

Hello! i found this shiny beetle in the jungle of the coast of Nayarit, México.
Signature: Ana

Dear Ana,
This magnificent Scarab Beetle is a Shining Leaf Chafer in the subfamily Rutelinae, and we are pretty certain it is in the genus Chrysina.  There are only four species represented on BugGuide from North America north of Mexico, but there are additional species in Mexico.  It might be LeConte’s Chrysina, Chrysina lecontei, which is pictured on BugGuide where it states:  “Considered by New Mexico to be a ‘Species of Greatest Conservation Need'”  Alas, we are unable to provide you with a species identification with any certainty even though 85 species are pictured on the Generic Guide to New World Scarab Beetles Chrysina Gallery, but another possibility is Chrysina quetzalcoatli which is also pictured on the Chrysina Gallery.  We will attempt to get an expert opinion for you.

Dear liza,
This is a Scarab Beetle, and we believe it is a Shining Leaf Chafer in the subfamily Rutelinae, and probably the tribe Rutelini which you can see well represented on BugGuide, a website that covers North American insects north of Mexico.

Letter 6 – Shining Leaf Chafer from Panama: Macraspis chrysis

Subject:  Jewel Scarab?
Geographic location of the bug:  Panama Canal Zone
Date: 09/24/2017
Time: 10:38 PM EDT
I found this beetle about 4 years ago while doing research in the forests in the Canal Zone of central Panama. It was dead laying along a stream bank, but I picked it up because I thought it looked cool, and have had it ever since. I’ve tried to find out what it is, but have had no luck. Looks like a jewel scarab, but the scutellum is larger than any I’ve seen. It’s an iridescent green, which turns to a red/orange when light reflects in certain ways. Any idea of what this is?
How you want your letter signed:  Andrew

Dear Andrew,
You are correct that this is a Scarab Beetle.  Perhaps the reason you didn’t have any luck with an identification is that you were searching for Scarab Beetles from Panama.  Nearby Costa Rica has many of the same insects as does Panama, but since there is more eco-tourism in Costa Rica, there tends to be better online databases for identifying the flora and fauna there.  Our first internet clue as to the identity of your Scarab Beetle was this Beetle Bling INBio posting on Jimmy O’Donnell’s Evolutionary Ecology site.  Though the species is not identified, there is an image from the collection of several dozens of what appears to be your beetle with this caption:  “A single specimen of a gold or silver Scarabs is impressive, but an entire drawer of them, lined up like a frozen army is incommunicably beautiful. Various descriptions were tossed around: gold and silver plated candies, gold doubloons, or ‘Beetle T-1000’.”  We then found an image of Macraspis chrysis on the Beetles (Coleoptera) and coleopterists site and clicking on the image produces this nice enlargement.  The species is also pictured on FlickR.

Wow! Thanks for the quick reply. I’m happy you were able to identify this particular beetle. Thank you so much for the help. This is a great resource for anyone with questions about a particular insect!

Letter 7 – Shining Leaf Chafer: Paracotalpa puncticollis

Weird green metallic beetle with white fur

I came across this bug while on a hiking trail in Sedona, AZ the other day. I’ve never seen anything like it and was wondering if I could get some help identifying it.
Michelle
Sedona, AZ

Hi Michelle,
We identified your Shining Leaf Chafer as Paracotalpa puncticollis on BugGuide, but the species has no common name.  Paracotalpa puncticollis is a new species for our site and it is not well represented on BugGuide either.  It is reported from California, where it was found on Juniper, and from Nevada where one photo shows it feeding on what appears to be juniper as well.  Thanks for sending your exciting image to our website.

Letter 8 – Little Bear: Paracotalpa ursina

Clare Marter Kenyon

Hi Clare,
Julian Donahue informed us yesterday at Janet’s going away party that you sent him a photo of this lovely Shining Leaf Chafer, which is why we gave you a hard time about not sending it to What’s That Bug?  It is Paracotalpa ursina, and BugGuide has a marvelous image of a mating pair also photographed on the Carrizo Plain, and it appears that they are also on phacelia.  CalPhotos, which you mentioned during our conversation at Janet’s party, calls it the Little Bear, a reference to the species name due to the hairiness of the beetle.

Letter 10 – Shining Leaf Chafer: Which Cotalpa species is it???

Large Beetle
Location: Western Colorado
June 5, 2011 11:16 am
Found this fairly large (1 1/4”) beetle on sagebrush in Loma Colorado. Area is high desert, 5,269 in elevation. Very striking yellow and orange leg colors. Have been looking for ID on internet, but really can’t find it. Any idea what this pretty beetle is?
Signature: Sage Hen

Dear Sage Hen,
This is one of the Shining Leaf Chafers in the genus Cotalpa, but several species look quite similar.  We believe it might be Cotalpa flavida which is represented on BugGuide from Utah and Nevada though on the genus page on BugGuide, it is listed as Arizona and California. Cotalpa subcribrata is listed from Colorado, however, BugGuide does not have any images of it.  An Eastern Species that is reported as far west as Texas and Nebraska on BugGuide is Cotalpa lanigera, the Goldsmith Beetle, which is believed to be the Gold Bug from Edgar Allen Poe fame.
