I found this on my deck. Can you tell me what it is? I have attached a couple of pictures.

It is the caterpillar of a Tiger Swallowtail, Papilio glaucus. This is a large, graceful yellow and black striped butterfly. The caterpillar is fond of wild cherry and other trees. Those false eyes are meant to scare hungry birds into thinking the benign caterpillar is a ferocious snake.

Well way cool. 🙂 I’ve been to the site you mention, an excellent resource. I note you had a request for a better picture of swallowtail caterpillars. I’ll attach one of my better ones, taken recently. These two are feeding on volunteer fennel in our garden. I’m not positive, but these are likely Black Swallowtail caterpillars. THanks again for the IDs. Wonderful site. Bookmarked. I’ll be back often. I’ll send a separate note with a photo of a click beetle for your collection.

I’m glad we could be helpful Jim. I don’t know if you have Anise Swallowtails, Papilio zelicaon, in your area. The caterpillars of Black Swallowtails and Anise Swallowtails look very similar. Thanks for the photo. It is pretty great.

Not a Rhinocerous Beetle?!
Hi there — I’m in south central Texas, and had the privilege of meeting this giant beetle! She looks like a June Bug, but way too big. As you can see, she doesn’t have the horned head, just a little round one, so I’m stumped! Any ideas?
Oh, and just for fun, here’s a shot of a red wasp trying its best to get this GIGANTIC dead spider into an eave of the house. I watched this wasp for at least an hour, during which time she dropped the spider at least twice and drug it back up the wall about 15 feet, all the way from the ground! Not a great shot, but I filmed a bit of this also, if you’re interested I can send the AVI file. I love bugs! Thanks for your great website.

Hi Debbie,
The females of the horned scarabs, are with the horns lacking, as in your specimen of a Dynastes tityus, sometimes called the Eastern Hercules Beetle, and sometimes called a Unicorn Beetle. Nice use of scale.

and something else I dont know what it is…
AWESOME site!
The other I have no clue what it is. It was taken on the shore of Lake Michigan at the Sleeping Bear Dunes National Lakeshore…there were hundreds of these hanging around. Any idea?

Hi Josh,
One of our beetle experts Dan, says this looks to be one of the Meloid Blister Beetles. The genus is Epicauta, the species indeterminate. The family includes the European Beetle that is used to make the aphrodesiac Spanish Fly.

Unknown Bug
Found this on my door and was curious if you could identify it for me. We live in North Central WV, and never saw one before. Thanks.

Hi Chad,
One of our contributing entomologists, beetle expert Dan, believes it to be Orthosoma brunneum, but it is impossible to be certain with your photo. The species, according to Dillon and Dillon “breeds in crossties, poles, and all structural timbers in contact with the ground or in moist, exposed situations. Adults are also attracted to lights.” That would explain the appearance on your door.

click beetle
Attached, photo of an “eyed” black and white beetle on the bark of an Arizona Ash tree, spotted (as it were) in Austin, TX on June 12, 2004. Perhaps an Eastern Eyed click beetle, Alaus oculatus?
Thanks for the great site, and service.
Jim

The Eyed Elator is surely a handsome Click Beetle. The scientific name is Alaus zuniatus (we aren’t positive on the spelling of the species name), found in the southwest. Thanks so much for the photo Jim. Keep sending us beauties.
