Hey Bugman,
I wrote the otherday concerning a bug I found digging holes. I have since been told that it is a great golden digger wasp. Then I checked your site and sure enough there it was…I never thought to look under Wasps. I thought I’d give you the photo’s in file format anyway so you can use them if you should desire.
Great site.

Hi Jay,
Since we can only post four letters in an hour, we must leave many letters unanswered. If we couldn’t open your previous files, they probably got discarded. We are happy your Great Golden Digger Wasp was identified and are happy to post your images. Thank you.

what bug
I saw this flying bug the other day. It was digging the hole in the ground in front of it. I’m pretty sure it was getting ready to lay an egg or eggs in it. When I came back later in the day the hole was filled in. I had seen one of these bugs a few days prior and it had a green catepiller that it had captured. (Unfortunately by the time I got the camera it was gone). I have an idea that it digs a hole, lays the egg or eggs and then puts prey in the hole for the larva to feed on but this is just a guess. I suspect it is some kind of hornet or wasp but can’t find it in my insect book. I live in south west MT

Hi G.,
You are good. This is a Thread-Waisted Wasp, Ammophila species. It lives in open areas throughout the US and Southern Canada. Adults feed on nectar and larvae eat hairless caterpillars and sawfly larvae. Female digs short burrows in sand or light soil, enlarges a chamber to receive immobilized insect prey, and lays an egg. Larva feed initially on nonessential tissues, later eats indiscriminately, killing host. Thanks for the great image. Try to get it with a caterpillar as well since the female will seal the nest and return with more food.

Great Golden Digging Wasp – Ky
I found a wasp digging in the back yard. From your sight it appears to be a Great Golden Digging Wasp. Last year I found a Cow Killer in my garage. Trying to identify that I found your great site. Keep up the good work.
Thank You,

Hi David,
Thank you so much for using the site as a research tool. So many people just send in photos and questions when a little searching will give them the answers. Your Great Golden Digger Wasp, Sphex ichneumoneus preys upon crickets, camel crickets and katydids. The adult builds the burrow and provisions 2-7 cells with anesthetized prey for the larval food. Adults frequent flowers for nectar and are active July and August.

Hi there.
I will try to get a picture of this creature for you…but untill then.. I will do my best to describe it to you in the hopes you can tell me what it is.
for starters..I live in Maryland (baltimore county) middle northeast md. and this creature has been spotted at work burrowing under the ground in our gardens and taking ever greens in with him/her. it is a large 1 1/2 inch to 2 inch wasp like creature with black wings (that flutter when its on the ground)…shapped like a wasp (redish in color with a heart shaped face and yellow hight lites on its face)…it flys more like a humming tends to hover and dart rather then fly around like a normal bee. it has been seen killing and carrying off katydids and other small-ish insects…they appear to have a huge under ground structure going with many holes comming up in the gardens….that are full of spreading ewes and now Stone crop plants. (use to have bulbs and ewes)..gardens have been untouched for about 30 years and the bee like creatures have been noticed since I planted the stone crop and cut away some of the ewes to reveal the soil. they are again…large wasp like with black wings and redish bodies…and seem to kill other insects. any ideas ? I will take a picture of them tomorrow

Hi Pat,
You have a Great Golden Digger Wasp.

Photo of strange tubular insect home
My fiance has recently moved from Michigan to Noth Carolina. It is amazing how many more bugs live in a sub-tropical climate! Anyhow, she is terrified of these nests she has founbd on her new deck. Can you identufy these nests? Is this something she needs to be aware of or something that presents a possible danger? Thanks for the help,

Hi Charles,
What a very large photo of a very large ceiling with a little Mud Dauber Nest in the center. These are solitary wasps that build nests of mud and fill them with paralyzed spiders, grasshoppers, leafhoppers, flies or other insects that serve as food for the young. Each species of wasp has a very specific food source. The wasps can sting, but will only do so if provoked, by say, a broom knocking down their nest.
Ed. Note: (09/06/2004) Eric just wrote in identifying the species as the Organ Pipe Mud Dauber, Trypoxylon politum, and informed us they prey on spides only.

Hi Bugman!
(Awsome site, BTW)We have new visitors in our yard (and in my camper). Large cylindrical bees or hornets, nearly 2″ long, black with three white stripes. They look like WWII fighters patrolling over London whenever you get near. Help! I’m ready to give them my tractor AND my camper!

Hi Russ,
I’m guessing Bald Faced Hornets, Dolichovespula maculata. These are social wasps that build a large paper nest from regurgitated wood pulp. The nests can be over a foot across that can contain 10,000 hornets. They are aggressive and do not like intruders near the nest and they will sting painfully, swarming and chasing the perpetrator. Unlike bees which die upon stinging, hornets can sting multiple times and live to tell. I hope you don’t have fields to plow or rubber to burn in the near future. I think your tractor and camper are lost to you until the frost which will kill the workers, but the queen hibernates and begins a new colony in the spring.

Hey, my friend found this weird nest/cocoon thing in his shed and its really weird and if you could tell us what its from thatd be great. Its grey and its made of like mud and clay and on the inside it was full of dead house was made in the secind story of his shed, and it was stuck to the side of the wall. the top was rounded with a closed hole and on the bottom there was an open hole. the walls are about about 3mm thick. the flies look like there trapped in some kind of webbing, but not.We live in a small town in Ontario canada. Were about an hour from toronto. Thats pretty much it. If you could get back to me as soon as possible thatd be great casue this thing is really gross and creepy. Thanks.

Dear James and Shannon,
You found the nest of a mud wasp. Your wasp prefers flies as food. I have a mud nest from the black & yellow mud dauber, Sceliphron caementarium. on my back wall and will post it with your letter in the near future. They generally sting spiders to fill the nest, then lay eggs on the paralyzed spiders and when the young wasps hatch, they have a fresh meal, eating the comatose spiders alive.
