The following specimen is identified on internet as C. speciosa from Concepcion Department, Paraguay, but I think it is more likely Cerodirphia apunctata, based on location and very obtuse angle to the "y".

Larve feed gregariously and have urticating spines.

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.

Here are two Cerodirphia larvae which may be of the same species, most likely Cerodirphia apunctata, but I am not at all certain as to species.
