Velvet Ant

unusual ant
This ant was found away from civilized area, in south central Missouri. I happened to see it on a trail for ATVs. The length of the ant is about the same as the diameter of a nickel. It was suggested to me that it may be a woodcutter, though nothing specific. I look forward to any information you can provide.

Your unusual ant goes by the common name Velvet Ant, but it is in fact a flightless female wasp. In the south, they are known as Cow-Killers because of the painful sting. The scientific name is Dasymutilla occidentalis.

Giant Ichneumon

What kind of insect is this?
Hello! I found this insect at my house located in Central PA. I think that it may be some sort of dragonfly. What is it?
Thanks!

Hi Eileen,
Thanks for sending in the great photos of Megarhyssa atrata, the Giant Ichneumon. Your female wasp uses that long ovipositor to deposit eggs deep inside living trees. Her young seek out and devour boring insects like sawflies. Though it looks dangerous, she will not sting you, despite being a type of wasp.

Great Black Wasp

To Whom it May Concern,
I killed two of these monsters this weekend. I have never seen a totally black, wasp like creature before. It dive bombed me and took an inordinate amount of wasp spray to kill. Can you please tell me what this is? I live in mid Michigan.
Thanks,
Chris McHugh

Hi Chris,
You killed Sphex pennsylvanica, the Great Black Wasp. They are hunters of katydids, and they nest singly in burrows in the soil, not in mud nests. They are very non-aggressive.

Mud Dauber Wasp

Wasp?
Hello, what is this insect? It has one pair of wings, the colors on it are black and yellow. I just thought it was odd that it’s abdomen was so skinny. It tends to fly quite slowly and it whirs whilst it flies. It is a wasp of some sort? Although the patterns of black and yellow are not striped, looks more spotted.

Hi T.
There is a reason “wasp-waist” has been used to describe a femine physique that has a tiny waist and awesome curves. Your Mud-Dauber from the genus Sceliphron also possesses a textbook thread waist. The species does have two pairs of wings.

Great Golden Digger Wasp

Hi,
I have another bug for you to look at. I was at work the other day and I saw this really big wasp digging holes in the walking path. He is about 1 inch long and extremely fast. I hope you like the pics.

Hi Ed,
Looks like you killed a Great Golden Digger Wasp, Sphex ichnumoneus. They hunt katydids and nest in burrows.

Velvet Ant

Yesterday, July 7, 2004, I was walking out of my garage with my two young sons (ages 20 mos. and 3 yrs.) and I turned my back for literally 20 seconds. My three year old comes running up to me and says his hand hurts. It looks dirty so I asked if he fell and he says, “a bug.” I asked if the bug bit him and he says no, but insists that his hand hurts. In order to distract him, I suggested that we get the mail. On walking to the mailbox, he says, “there it is!” I look to my right and see this bright red bug walking on the driveway. The bug was 3/4 inch long, I would guess, and the brightest red I have ever seen. Mostly red with black legs and, I would guess, three black stripes. I was startled and afraid as I do a lot of gardening and have never seen anything like it, so I stomped it with my shoe. I had to run an errand, but about 30 minutes later I checked my son’s hand as I was worried because the bug looked so wicked. His right thumb had swelled to about 1.5 times the size of his other thumb and was very hard/tight. It also had a white tiny pin prick in the middle of the fatty part of his thumb. I started to panic a bit, but within another half hour, the swelling started to go down and he said he was “all better.” When I got home, I started to dig for information on the internet and after two hours found your site. Part of my problem was that I thought I had seen a beetle of some sort so I typed in red bug (which came up with chiggers), red beetle (which came up with a red milkweed beetle, sort of close but not quite right) and red locust (which was definitely not what I saw). The body was segmented in three parts and I thought since it was crawling that it could not be a bee. After finding your site, I took tweezers and a white envelope and went to see if the bug parts were still in any shape to take a photo. I collected the bug and noticed it was very furry and in particular it had sort of longer legs than I had originally thought that were also furry. It was not as red as when I saw it walking, but it had been about four hours in the hot Georgia sun. I showed it to my husband when he got home and he said it looked like a wasp or hornet so I came back to your site and saw a picture of the bug I think I saw – a Velvet Ant, listed under wasps. I have become fascinated with your site since yesterday and read many clips just to learn more. Once I had a name for the bug I saw, I tried to find more information via several search engines, but with little success other than some pictures. My son seems fine now, but more of the story continues to come forth. He told me today that “the red bug was walking in the grass and (he) tried to pick it up.” Yikes! He also told me that he isn’t “supposed to touch bugs without asking Mommy because it might bite (him).” I guess maybe a good lesson for him since he is fascinated with all wildlife and touches without thinking usually. Anyway, none of the sites I could find really listed if a sting by a Velvet Ant is harmful, other than the pain. Do you know? Are they common in Georgia (we live in Forsyth County, north of Atlanta)? Do they change color (become a brighter red than normal) when they have been messed with or picked up? Are the males the same bright colors as this female was? Do you think I will see more? If I do see another one, I will try to snap a picture to send to you. After seeing your site, I felt guilty for killing it. It would have been a very good picture, I think. Thanks for your site!! Sorry for the “long version” of my story,
Stephanie Moore
PS. I saw an email by Eric Eaton referring to www.bugguide.net as a good source for info. In this case, it was not very helpful for me (I am a bug idiot, more or less). Although, I did see that some of the pictures of the Velvet Ant that were posted were taken in Georgia, which answers that question I guess.

Hi Stephanie,
Velvet Ants are female flightless wasps. The males are smaller and have wings. There are many species of Velvet Ants, and some are bright red, others orange and still others yellow. The sting is painful, but not serious unless there is an alergic reaction. I love the name Cow Killer for the species Dasymutilla occidentalis, which is common in the South. Perhaps another websearch with the scientific name will give you additional information. I am very happy our site was helpful.

Megarhyssa nortoni

Giant Ichneumon
I found this wasp name while searching your web site for pictures to identify a "bug". Now I cannot sleep until I know more about this wasp….if of course I have identified it correctly. You called it a "Giant Ichneumon" in response to an email sent to you by someone else. I think I have one under a glass in my family room….too afraid to move it. I have 3 kids and a dog. This wasp has a black skinny "tail" that is at least 2 inches long and 6 legs that are orange/yellowish and a long skinny body. Did I mention the long antennas? When I look up Ichneumon as a general web search…I don’t get to far with any additional info. What do I do with it and are there many more lurking about? AAaaaghhhh! We live in the pacific northwest. Thanks for any info. I did take pics and will send one on if you need to see it. Thank you in advance,
R. Frances

Dear R. Frances,
Though they are wasps, Giant Ichneumons do not sting. That is an ovipositor for laying eggs deep inside trees where the larvae hunt wood borers. They are beneficial insects for that reason. Try doing a search for the scientific name Megarhyssa atrata for more information.

Photos of Megarhyssa nortoni
Hi Daniel,
Thanks for your quick response….here are 6 lovely photos of the Megarhyssa atrata or Giant Ichneumon. So glad to hear that the tail is not the stinger!! And you will be glad to note my husband released her this morning to the outside. Kinda curious where they are originally found as I have lived in the Seattle area for 30 years and have not seen one here before. Thanks Daniel!

Hi again R. Frances,
After seeing your photos, we can agree they are an Ichneumon of some sort, but the coloring seems a little off for Megarhyssa atrata, though it could be a local variation.
Ed. Note: (09/06/2004) Eric just wrote in identifying this as Megarhyssa nortoni.

Ichneumon Wasp

Hi. I wonder if you could let me know what these are, I live in the UK, and have looked up several books and Web sites but can’t seem to find them.
Thanks
