Around the place where I live there is a squadron of hummingbird-sized hornets or bees. They dig burrows in the ground, typically alongside concrete foundations or under landscaping stones and wooden planters, and seem to spend a lot of time hovering over their burrows. I’m not joking about their size: When one landed on my windshield (a startlong experience!), I took the oportunity to hold a business card up to it (it was outside, I was _inside_, thank you!), and d\*mn if it wasnt _longer_ than my card, making it at least 2 1/2 inches long. It had a nasty-looking point on it’s abdomen, which I assume to be a stinger, was mostly black, but had “spilled paint” style markings in a dull-yellow collor, and was as big around as my index finger.

What the heck are these? Do they sting? If so, how badly? Are they known to be aggressive? Should I be setting up anti-aircraft weapons? Calling for the combat air patrol?

I’ve seen these things lately too. I have lived in Chicago for four years and lived in Michigan before that and have never seen these things before. A whole bunch of them just seemed to show up around the building I work at, burrowing nests around the sidewalks. Anybody know what they are?

I forget what they are called, but I had a slew of them outside my old job (Atlanta, GA) and although they are very large and nasty-looking, they were never aggressive and would always buzz out of the way when you walked by. They came back evey year around a certain time in the spring or summer and would hang around for a few months, then would disappear again.

Can’t speak for Tranquilis, but what I was talking about wasn’t a cicada. It was similar in size, but is looked just like a huge hornet.

Nah, cicadas are well known, and only about 1/3 as large as these. Also, they can’t hover.

Got it!

they are cicada killers…the arch-enemy of the pesky cicadas.

They might be Cicada killer wasps:

Thanks folks!

I have to say though, either I’ve got giant mutant Cicada Killers, or the factsheet isn’t fully up to date. The mosnters I’ve got buzzing about are more on the 7 to 8 cm size, rather than 5 cm.

Well, cool…

I can stop freaking now.

The only wasp or hymenopteran type insect in that size range or larger in the United States is a Tarantula Hawk and they aren’t any of those in your area. 2.5" + is too big for even the largest hornet or bee except maybe a queen. Do they have a “pinched” waist like wasps or more of a cigar shape?

Per the other poster they might well be cicadas.

Do they look like this

Blush. Never mind that last post.

While whistling casually sweeps assertion of fact about wasp size under the rug hoping no one notices.

Nope. I’m quite familiar with cicadas, and if you look at **Squink** ’s first link, you’ll get a beautiful picture of exactly what I’m talking about. I only measured the one wasp, and that was via the guage of my business card, which is 2 1/2 inches long. I suppose it may’ve been a mutant, but I don’t have a proper scientific sample to be sure.

Is there significant sexual dimorphism in Cicada Killers?

We had these things at my family’s house in Houston. I _hate_ wasps. These things buzz in a very characteristic manner, that still causes the “fight-or-flight” reflex in me.

_shudder_

D\*mn, **Squink** , where do you _find_ this stuff?

Thanks!
