Subject: Ivory-marked Beetle?
Location: Northeast Florida
July 29, 2012 4:15 pm
I’ve never seen a bug like this before. It was sitting in the shade on the door of my shed this morning when I went out to mow the grass. It was still in the same shady spot in the middle of the afternoon. When the sun hit that area the beetle began to move around and left. It was about an inch long with very distinctive markings. I hunted through beetles on Bug Guide and I think this is an Ivory-marked Beetle (Eburia quadrigeminata). The markings match but the body color is a little different. Can you help?

Possibly Ivory Marked Beetle

Hi Karen,
This is the third Longhorned Borer Beetle in the family Cerambycidae that we are posting in a row this morning.  This might be an Ivory Marked Beetle,
Eburia quadrigeminata, though there are other members in the genus Eburia that look very similar.  We could not discount that it might be Eburia distincta, a species that feeds on Cypress trees and which BugGuide only reports from Florida.  There are also several other species in the genus that are only reported from Florida.

My husband sent me a text with this picture of a large black and white striped beetle with incredible antennae (also striped)and asked me what it was. I work in fisheries but have no idea when it comes to bugs, so I did some internet searches and could only find pictures of beetles with more mottled black and white coloration, not the very distinct stripes this guy has. Just wondering if you guys can tell me what it is?

Banded Alder Borer

Dear curious ichthyologist,
This might well be our favorite North American beetle, the Banded Alder Borer.  It is found in the western portion of North America.  It really is a stunning looking beetle.

I want to make sure this is not a quarentine bug if I am to let it go. I live near Worcester, MA which has the ALB problem.

Red Oak Borer

Hi Paul,
This is a native Longhorned Borer Beetle in the family Cerambycidae, the same family as the Asian Longhorned Borer (ALB).  When species are introduced to new locations, they often do not have natural predators and they can become problematic invasive exotic species.  Native species, though they sometimes damage the plants that they are feeding upon, are generally not thought of as threats.  We believe based on BugGuide images that this might be a member of the genus
Goes, perhaps Goes debilis.  According to BugGuide, the members of this genus are:  “Typically twig girdlers or stem borers.”  We are going to try to get a second (and possibly third) opinion on this identification by contacting Eric Eaton and Doug Yanega.

Red Oak Borer

Eric Eaton Makes a Correction:  Red Oak Borer
Funny, this *is* the same species as the other:  Red Oak Borer, Enaphalodes rufulus, but female this time.  Pretty certain of the species ID, anyway.

We have posted this picture on facebook to try to have it identified, so far people think it is either a crane fly or walkingstick, however I am unable to find an image of either that matched the picture taken
the picture was taken around 3pm just south of London Ontario. It was perched on a doorframe.

Please forgive me if these two photos have been previously received. I attempted to submit these late last week, however I didn’t get a confirmation E-mail so I’m not sure if my submission was successful.
The photos were taken on Sunday July 22, 2012. The first one was taken at Palmyra Cove Nature Park in Palmyra, NJ. (Had I realized that August’s bug of the month was the cow killer I would have taken a few photos of that species when I was there yesterday.) It took two trips to the park and three encounters with this particular species of velvet ant before I was able to get a photo of it.
The 1st time we came across one, she ran and hid in her burrow before I was able to get my phone out and snap a photo.
The 2nd encounter was in a grassy area & due to the grass obstructing the wasp I wasn’t able to capture a photo. I tried to coax her out into the open using a small twig, but she started to make an audible squeaking sound that told me that it was time to back off.
Finally on the third encounter, we found one in an open sandy area. Though she tried to run, she had more than enough space to run for me to have the time to get out my phone and take a picture.
After doing some research, with the aid of your site, I believe that I’ve identified her as Dasymutilla Vesta. Though, I could easily be wrong as I am no expert on insects.
After returning home from the park I noticed this pair of what I believe are black and yellow mud daubers trying to get busy on the Helenium that I planted a few years ago. Though, I’m not sure if the female was interested. The male was jabbing away furiously at the female’s abdomen but he never seemed to find his mark. Perhaps we killed the mood by barging in on them, or perhaps she had a headache.
I’ve taken a few other photos of some other insects at Palmyra Cove that I wouldn’t mind sharing with you, provided that multiple submissions from one individual wouldn’t be a nuisance. I honestly think that I’m one of the few people who go to that park mainly to see the insect life over any of the other wildlife that lives there.
Thank you for your time.

Velvet Ant

Hi Dave,
Thanks for your persistence.  We did receive your original submission, and we intended to post it, but alas, we didn’t get to it and suddenly your email got buried under the deluge of summer identification requests we receive.  Thank you again for resending.  We cannot for certain identify the Velvet Ant to the species level, but another possibility based on BugGuide images and range information might be the genus
Ephuta.   We have heard the squeaking noise you describe and for such tiny creatures, Velvet Ants are able to make a disproportionate amount of noise.  We will nonetheless tag this as a Bug Love entry even though you didn’t actually capture the mating act with your camera.  We would love to receive other submissions from you, especially of species that are not well represented on our site or images that are exceptional for other reasons.
Please in the future, only submit one specimen at a time.  We like to have each posting be a distinct species unless there is some relationship between two species that is significant.
