Another Unicorn or False Unicorn Caterpillar

Caterpillar found in blueberry bushes
September 23, 2009
I found this caterpillar taking a ride on my son’s shirt during an early morning of blueberry picking. I took its picture on my finger to show the size, and then we happily set it back onto a blueberry bush. I can’t find an identification for it. Thank you!

Unicorn Caterpillar, or imposter???

Unicorn Caterpillar, or imposter???

Hi Nichole,
Interestingly, we just finished posting another photo of a Unicorn Caterpillar, or False Unicorn Caterpillar from the genus Schizura.  Your photo with the translucent talon, we mean fingernail, is awesome.

Red Hump Caterpillar

Hi J,
We believe this to be a Red Hump Caterpillar, Schizura concinna, a species of Prominent Moth.  The caterpillars, according to BugGuide:  “feed on a wide range of woody plants.

Unicorn Caterpillar? or False Unicorn Caterpillar, perhaps??

Unicorn Caterpillar
September 23, 2009
Was walking with the 2 year old in the swamp park in Southern Illinois today and found a strange looking caterpillar. Some research has it as a Schizura unicornis (I think…do they eat oak?).
The camouflage was strikingly good from some angles, the green “window” in its mid-section is exactly as translucent as leaves with the sun behind them.
Thought you might like some pictures.

Possibly Unicorn Caterpillar

Possibly Unicorn Caterpillar

Dear Bert,
BugGuide lists the food plants of the Unicorn Caterpillar as:  “alder, apple, Trembling Aspen (Populus tremuloides), White Birch (Betula papyrifera), elm, hawthorn, hickory, willow
“, while the closely related and similar looking Morning Glory Prominent or False Unicorn Caterpillar has its food plants listed as:  “leaves of beech, birch, elm, maple, morning-glory, oak, rose, and other woody plants” on BugGuide.  We would entertain the possibility that the list of plants for the Unicorn Caterpillar might be incomplete, and that your caterpillar might be either species.

Purple and orange caterpillar

Hello,
I found this odd little caterpillar on a Black Locust tree near my house in south-western Pennsylvania. I tried searching through books and the internet, hoping to find out what this little guy is with no luck. [S]he is about 2″ long. Hopefully you can help identify the bugger!

Black Spotted Prominent Caterpillar

Dear Rebecca,
We started by searching the Owlet Moth Caterpillars on BugGuide, and then progressed to the Prominent Caterpillars.  Eventually we identified your Black Spotted Prominent Caterpillar, Dasylophia anguina, on BugGuide.  Distinguishing features according to Craig Biegler on BugGuide
include:  “the black ’shoulder’ spot, shiny black ‘button’ on A8, raised rear end, elongated anal prolegs.“  The Caterpillars of the Eastern Forests website indicates:  “Splendidly rendered in shiny lavender, orange (or red), yellow, and black; both color and pattern variable. Head orange and unmarked. Middorsal and 2 or 3 subdorsal and supraspiracular stripes, these thin, broken, and black; subdorsal stripe orange, broad; spiracular stripe lemon, broad. Eighth abdominal segment with black dorsal button. Subventer with line of raised shiny black spots just above legs. Food: lead plant, locusts, and other legumes. Caterpillar: June to October; apparently 2 generations.”

Red Humped Caterpillar

Caterpillars feeding on speckled alder

Hi!
I really like your website – it’s been very helpful in identifying many of the insects that I’ve found. These caterpillars I’m having a hard time with though. I saw them during the summer, munching on speckled alder leaves on an island in Georgian Bay. As you can see in the photograph, they are yellow, black and white striped, with reddish orange heads and a big reddish bump a little ways behind the head as well. They have several hairs and stiff black spikes along them. Do you know what they are?

Hi Kristin,
It took us a bit of searching before we were able to identify your Red Humped Caterpillars, Schizura concinna, but we eventually located it on BugGuide where it is described as:  ” has bright red head and red hump over segment A3.  Striping is variable but includes black, yellow and white pinstripes.  Takes up a defensive posture raising the rear end when disturbed. ” This is a Prominent Caterpillar in the family Notodontidae.

I found this character hiding in a willow tree today. He hooks his tail around like a scorpion in a treatening manner when I stroked his back with a leaf.

White Furcula Caterpillar

Dear Wondering,
Your caterpillar is one of the Prominent Moth Caterpillars, most probably the White Furcula, Furcula borealis, based on images posted to BugGuide.

Azalea Caterpillars, probably

Do you know what kind of caterpillar this is? They were on our blueberry bush!

Datana Caterpillars on Blueberry

Datana Caterpillars on Blueberry

These are caterpillars in the genus Datana.  Datana major, the Azalea Caterpillar is most likely and they appear to be early instars that will get more colorful as they grow and molt.  You can read more about this species on BugGuide, where it is reported that they are sometimes found on blueberry leaves.  The posture and group grazing of this genus are quite unique.

Prominent Moth Caterpillar

unknown caterpillar
We aren’t sure if this came out of our greenhouse or from one of the trees in our yard. It is approximately 2″ long. We live at Moose Pass, Alaska, on the Kenai Peninsula.

This is one of the Prominent Moth Caterpillars, possibly in the genus Furcula.

Azalea Caterpillar

beautiful caterpillar
My husband and I found this on a blueberry bush. As soon as we touched the branch, “he” assumed this defensive posture, curling up and emitting a drop of liquid from end back end. It’s a beautiful creature, but what is it? I’m sorry but I wasn’t able to place the photo into this e-mail, other than attaching it. I hope you are able to open the document. Thank you

Hi Sarah,
Despite being named the Azalea Caterpillar, BugGuide indicates that Datana major can also be found on blueberry.

Hi again Jeannette,
Thanks for sending us another photo of another Puss Moth Caterpillar, Cerura vinula. Many typically green caterpillars change colors, often to brown, red, orange, pink or purple just before pupation. We suspect that is about to happen with this individual. We will address you moth query in a separate email.

Prominent Moth Caterpillar

unidentified caterpillar
Hello What’s That Bug:
Some months ago, I was photographing bugs and stumbled upon two odd looking caterpillars. At first they appeared to be a chrysalis, but they were moving and when I looked closer they were caterpillars. I was wondering if you could identify the caterpillar for me. Here is a link to the picture I took:Thanks in advance for any information,
Michael Thompson

Hi Michael,
Where in the world was the photo taken?

In south Texas near San Antonio…it was just crawling around in my backyard. There were two of them eating on the same plant. I don’t know what the plant was, but it’s some kind of weed, with large, serrated-looking leaves. The caterpillars were about an inch and a half long at most, gray in color, and had humps on their backs which appeared to be tipped with stingers of some sort. The photograph was taken just Northeast of San Antonio Texas in late summer.

Hi again Michael,
This is a Prominent Moth Caterpillar in the genus Schizura, probably Schizura ipomoeae, the Morning Glory Prominent.
