Brown bug with white spots on back
July 29, 2009
I recently found this bug crawling on my floor. I grabbed my camera as I”ve not seen it before. It had 4 white spots (the image below shows 2) that looked to be pretty symmetrical.
The antenne are about 3″ long or so.
To give an estimate, it’s about 2″ long
I found this just now (Jul 29, 2009) in Missouri.

Ivory Marked Beetle
Hi Matt,
This is an Ivory Marked Beetle, Eburia quadrigeminata, a species in the family Cerambycidae also known as the Four Marked Ash Borer. BugGuide has some information on this species including: “Larvae bore into heartwood of deciduous trees, esp. ash, hickory. May emerge from finished lumber years after milling.”

I was trying to identify this huge beetle that was on my porch June 11th. I found it here and am very greatful. I was scared to walk past it!

Giant Stag Beetle
Hi Stefanie,
When we made the Giant Stag Beetle, Lucanus elaphus, our Bug of the Month, we thought we would get several more submissions. Yours is the only one we received, though we got many images of a close relative, the Reddish Brown Stag Beetle.
(Believed) female Eastern Hercules Beetle, second photo turned out very good

Hi,
I believe this is a female Eastern Hercules Beetle, but I’m not totally sure. It was found on the side of my house in the evening. I live in middle Tennessee. I know you have posted some of these already, but I think the second picture turned out really well.

Hi Matthew,
You are correct. This is a female Eastern Hercules Beetle, Dynastes tityus. The close-up is an interesting angle.

I knew that subject line would get your attention. I recently took some pics worthy of your BUG LOVE page, but I didn’t know what kind of beetles they were. Then today I checked your site and there it is- a banded longhorn. If you care to zoom in a bit you’ll understand the subject line.

Mating Longhorns
Dear Vince,
These mating beetles may be the Banded Longhorn, Typocerus velutinus, or they may be one of the 15 other members of the genus identified on BugGuide. According to BugGuide: “Prominent genus of flower longhorns. Many, if not most, have a zebra-like or spotted pattern. This is probably mimicry of hymenoptera. Several are distinctively marked on elytra: T. velutina, zebra, lunulatus. However there is some variability, some T. velutina, in particular, are weakly marked. Other species must be identified under magnification or from very high-quality photographs. These include T. acuticauda and T. deceptus.“ Thanks for sending your graphic photo of a mating pair.

Here is a Banded longhorn, Typocerus velutinus. It was eating pollen and, or nectar. This is the first one of these I’ve seen.

Banded Longhorn
Hello again Terry,
WE really appreciate receiving your image of a Banded Longhorn. IT is not well represented on our website. According to BugGuide: “Larvae feed on decaying hardwoods such as oak, hickory. Adults usually found in daytime, but do come to lights, so probably somewhat nocturnal.“

I found this beautiful bug in my garden, and I almost thought it was fake until it flew to one of my plants. I have never seen anything like it, the detailing was amazing, One picture is of the underneath and one from above. Thanks!

Shiny Olive-green 3-inch…Beetle?
July 23, 2009
I did not kill this bug!! He was lying on our bumper when we got out of our car at the New York Aquarium in Brooklyn, New York (right by the water on Coney Island). We had driven up from the Washington, DC, area that day and I’m not sure how long he was on board. He was about three inches long and a shiny olive color. If you could just get me started I’m sure I could find him, but all my searches turn up metallic looking bugs, which he was not. Thanks you!!

Giant Black Water Beetle
Hi Hawke,
This is some species of Water Beetle, either a Water Scavenger in the family Hydrophilidae, or a Predaceous Diving Beetle in the family Dytiscidae. According to BugGuide: “Water scavengers have keeled sternum, come up for air head first. Diving beetles have unkeeled sternum, come up for air tail first.” We are inclined to ID this as the Water Scavenger, Hydrophilus triangularis, which BugGuide describes as: “Large, shiny black with olive tinge. Underside with prominent spine (prosternal process). Similar to the usually smaller H. (Dibolocelus) ovatus. H. triangluaris is more oblong, H. ovatus more oval. H. ovatus is more common southward.” The common name is the Giant Black Water Beetle.
Confirmation from Eric Eaton
Daniel:
The giant black water beetle is indeed Hydrophilus triangularis.

Found this picture http://davesgarden.com/guides/bf/showimage/5301/ which sure looks like him.
Thanks! I was stumped.
My husband says he saved him to put by the computer… if he is intact I’ll try to take a better picture. He was quite an impressive creature and I didn’t see any others on What’s That Bug.
Thanks!

Was camping in Northern california last weekend. Mendocino national forrest to be exact and we found this scurrying on the ground. It was huge and vicious. I would love to know what kind of bug this is? and how common these are? Thanks for your time.

California Root Borer
Dear Max,
This is a female California Root Borer, Priunus californicus, and common is a relative term. The species is not uncommon, but populations may fluctuate from location to location. We just returned from camping in the Mendocino woodlands and we were not fortunate enough to see a California Root Borer.
