Unidentified Yellow Caterpillar - Dasylophia anguina

Unidentified Yellow Caterpillar - Dasylophia anguina
Geneseo, Henry County, Illinois, USA
July 23, 2005
I found this beautiful caterpillar today and have no idea what it is. Any help is appreciated.

Please contact us by email (see our contributor page here) regarding permission to display on Plates at Moth Photographers Group photographs of moths and larvae that you have posted here at BugGuide. Thanks, J&J.

Sure You Can
John and Jane, I tired to pm you, but it keeps telling me that your email is not valid and won't send. Hopefully you check this. You most certainly can use my photo for your purposes. Thanks for asking.


You would have to adjust the text listed
until it looks like an email address with @ instead of AT, etc. Please try again so we can see if we can communicate offsite. And where are all those new images, Bill? We keep waiting to see what's happening out there in western Illinois and you're keeping us in suspense!

I'm convinced this is an early instar of Dasylophia anguina. While I haven't seen any specimens as yellow as this one, the black "shoulder" spot, shiny black "button" on A8, raised rear end, elongated anal prolegs and other features scream "black-spotted prominent." Ignore the coloration and just compare physical features on these guys:

And here's the green form, though still not as yellow as yours:

Wagner lists sweet clover as a foodplant. Hope this helps, even with the year-long delay!

Nice catch!
We were nowhere on this one, yet it's certainly a good match for the second image you posted.

It looks a lot like a Hyles lineata, but is too yellow. However, it is in the process of molting or has just molted to a larger skin as evidenced by the old head capsule/shell next to the real head.

Plant ID
Can you identify the plant species? That often helps. Are we looking at seeds forming on a sweetclover?

Sweet Clover
Yes, this plant is sweet clover. I should have put that in when I posted. Thanks.
