Large Predatory Wasp

Every year without fail a few large wasps make burrows around our yard and attack anyone who dares walk past. We were under the impression they were cicada killers, so we left them alone up until now. This one burrowed right by the door, and went after me, so we have to kill it to make sure it didn’t go after our 1 year old daughter. To our surprise, it is not a cicada killer, but it is scary. What is it?

Great Golden Digger Wasp Carnage

Dear Therese,
This poor dead creature is a Great Golden Digger Wasp.  They prey upon Katydids, which they sting and paralyze.  Then the Katydid is dragged to a burrow and buried after an egg is laid upon it.  Adult Great Golden Digger Wasps are pollinators.  They are a beneficial species and it is our opinion that they should not be killed because of the fear of a potential sting.  It is also our opinion that if your one year old daughter managed to let herself out of the door, there are far greater dangers awaiting her in the world than a solitary wasp that is trying to provide for her own brood.  Solitary Wasps do not tend to be aggressive, and the chances of being stung by one are not very great.

found this green moth on the outside of my house. Small…probably half inch to an inch wide. Looked like a little red on middle of body between wing areas.

Dear Georgi,
This is one of the moths in the family Geometridae.  The subfamily Geometrinae contains the Emeralds, many of which look quite similar to your moth with its green coloration.

Williams Tiger Moth?

Hi WTB! You have many beautiful Tiger Moths on your website, but I didn’t see the Williams Tiger Moth – Grammia williamsii. My sister found this one on her porch today, in the prairie foothills southwest of Denver. At least I THINK it’s a Williams Tiger Moth… am I right? 🙂

Williams' Tiger Moth, we believe

Dear Katie,
The markings on your Tiger Moth look very similar to the markings on the photographs of the Williams’ Tiger Moth,
Grammia williamsii, that are posted on BugGuide, and BugGuide has data indicating that there have been sightings in Colorado, however, according to BugGuide, there are 38 species in the genus Grammia in North America as well as numerous subspecies.  Since many of the Tiger Moths in the genus Grammia look quite similar, this may be a near relative of the Williams’ Tiger Moth.

I took this picture on Whidbey Island, WA. near the beach. I did some research and found the name, thought you would like this picture.

Hi Christina,
The last image we received of a Banded Alder Borer was not of the greatest resolution, and we are very happy that you have supplied us with a recent high quality image.

Insect Colony on Pine Tree
Location: Millville, PA

It’s a hot July day in central PA. I discovered several colonies of a tiny insect on a pine tree. Each colony had hundreds of bugs. About 1/8” long, the predominant color is a series of yellow-gold stripes across the back. The body looks gray or black. There are long antennae that are pointed at the ends. They don’t seem to fly. Would like to know what this is, and if it is bad for our tree!

probably Bark Lice

Dear alice,
We cannot make out the detail in your image, but we suspect these are benign Tree Cattle, a common name for Bark Lice that we really like.  They feed on lichen growing on the tree and they will not harm the tree.  See this posting from our archive to compare:

Hello, I have photographed this Treehopper in Brazil, Northern Pantanal.
Shearching the Internet, I have found this page and thought mine was very similar.
I liked the site and decided to register to try to ID this…

Unknown Treehopper from Brazil

We still do not know the identity of this spectacular Treehopper, and perhaps this additional posting will lead to a proper species identification.
