Banded Tussock Moth Caterpillar

Dear Stephanie,
This looks like a Banded Tussock Moth Caterpillar,
Halysidota tessellaris, to us, and though it is a variably colored caterpillar, it does match the individual in this BugGuide image.  According to BugGuide:  “Larvae feed on leaves of alder, ash, birch, elm, hazel, hickory, oak, poplar, tulip tree, walnut, willow.”

Variegated Fritillary Caterpillar

Dear Sharon,
We believe this is a Variegated Fritillary Caterpillar and according to BugGuide:  “Larvae feed on Violets & Pansy (
Viola), Flax (Linum), Passion Vine (Passiflora), Damiana (Turnera), Moonseed (Menispermum), Mayapple (Podophyllum), Stonecrop (Sedum), Purslane (Portulaca) and others. Adults are fond of flowers, and especially seem to like Thistles and yellow Composites. They also frequently visit damp ground.”

Modest Sphinx Caterpillar

Dear PH,
This is the caterpillar of a Modest Sphinx or Poplar Sphinx,
Pachysphinx modesta, and we identified on Sphingidae of the Americas where it states:  ”  These hornworms feed upon poplar, willow, and cottonwood, are very strong and develop to quite a size.  Larvae progress very rapidly on poplar. The green of the early hornworm instars is very much like the top of the poplar leaf while the pale green of the final instar more closely resembles the color of the underside of poplar leaves.  Larvae are extremely strong with powerful mandibles.”  The caudal horn on the Modest Sphinx Caterpillar is quite insignificant compared to the horns of other caterpillars in the family.

Unknown Hornworm

Dear Sarah,
We are very confident that this is a Hornworm in the family Sphingidae, and that it will eventually transform into a Sphinx Moth or Hawkmoth, but alas, we have not been successful identifying its species despite the excellent database on Sphingidae of the Americas.  We will write to Bill Oehlke to see if he can provide a species identification.

Bill Oehlke Responds.
Hi Daniel, I think I have seen that one before, but a quick check did not let me come up with an id. Later this afternoon I will send it to Jean Haxaire to see if he knows what it is.
Bill

Daniel,
Jean Haxaire has indicated Isognathus rimosus inclitus.
I wish permission to post it to website. Please check with photographer and forward his or her name.
Bill

Ed. Note:  The subspecies Isognathus rimosus inclitus is pictured on Sphingidae of the Americas, but there is no larval image.  We are writing back to Sarah with the identification and a request from Bill Oehlke to include the image on his comprehensive site.

Hi Daniel,
Thanks so much. I’m checking with my friend and am getting an exact location if possible. I’m sure she’ll be alright with sharing, but will get back to you tomorrow.
Sarah

Hi Daniel,
Pilar Martinez is the photographer and the pic was taken in Chapala, Jalisco , Mexico
Pilar has said ok to sharing the image. I’m copying her on this email.
Thank you so much for the identification and glad to contribute to the database.
Please send us a link when it’s up.

Thanks Sarah and Pilar,
Pilar’s image is already live on What’s That Bug? and Bill Oehlke will post it to the species page for
 Isognathus rimosus inclitus on his site, Sphingidae of the Americas, where he has adult moths of  pictured, but no caterpillars.
