I would like your help in identifying this species of caterpillar. Has you can see in the photos, is body is bright orange with some sort of clack spikes and little black hair all over the body.
They appeared on a creeper-weed like plant, and seems to be quite the number on them in a small area.
Its summer in here, with days with high temperature and high humidity and rains, so it’s possible the plant and/or the bugs are travelers of these stormy weather.
Thanks a lot for any input in the mater.

We have not had any luck finding any matching images online from Argentina, but your caterpillar reminds us of the Polka Dot Wasp Moth Caterpillar or Oleander Caterpillar, Syntomeida epilais, a species found in the Caribbean and in Florida. We believe your individuals are either members of the same genus, the same subtribe Euchromiina or a member of the Tiger Moth tribe Arctiini, depending upon how closely they are related. Perhaps one of our readers will be able to assist in this identification. Knowing the name of the “creeper-weed” upon which they were feeding might help.
Update: March 16, 2016
Today we got a comment from Eduardo that included these two images. Our general identification remains unchanged, and this is most definitely a Wasp Moth in the subtribe Euchromiina. We will check with Julian Donahue to see if he can provide an identification.
