Correction: White Rayed Patch Caterpillar, NOT Pine Moth Caterpillar from Mexico

Ed. Note:  28 February, 2016
We received notice from Peculiarist that the same caterpillar was submitted for twice for identification.  The correct identification is most likely a White Rayed Patch caterpillar.

Hi,
I took this photo on October 2014 in Cuernavaca, Mexico. I think it may have been on milkweed, but I’m not a hundred percent sure about that. I’d appreciate any insights.

Possibly Buck Moth Caterpillar
White Rayed Patch Caterpillar

Dear Peculiarist,
We believe this is a Buck Moth Caterpillar in the genus
Hemileuca, but we have not had any luck locating any matching images of Mexican species with such dark coloration with yellow speckles.  We will contact Bill Oehlke to get his opinion.

Daniel,
I am pretty sure it is one of the Coloradia species, and the only Coloradia I have for Morelos is Coloradia euphrosyne. Unfortunately I d o not have an image for comparison, but I will tentatively post this image to that page. As always I request name of photographer and permission to post.

Daniel,
Elevation and date might also be helpful if you can obtain that info. Euphrosyne are known from elevations around 2000m and are thought to be pine feeders although the larval stage has not been documented to my knowledge.

Thanks for the identification! I gladly give you permission to use the image for the site.
And thanks for the site, it’s very helpful to me, as I try to figure out what’s in my garden.

Update from Peculiarist:  February 27, 2016
Hi Daniel,
As I was updating my page I noticed that this is the same caterpillar I sent before (my photo folders are a bit of a mess, and I had this duplicated in another folder), that was tentatively identified as a Pine Moth caterpillar. They do look alike, but I think with the extra information you have in these three photos White-rayed Patch is a more likely match. The food tree matches.
Thanks for your help, and I’ll be more careful in sending the most complete information I can in the future.
James
