Behavioral nude women of Caxias do sul and Caxias do sul of another last instar aggregation were observed in the field. The ecloding larvae were fed with plantain, but survived only until the third instar, indicating that it is not a viable host plant. The remaining larvae, from aggregations collected on capororoca, were kept in screened cages Caxkas fed with leaves from the plant.
The first aggregation 1 consisted of 17 fourth instar larvae collected on the trunk of an adult plant located in a sunny place along the campus access road, quite different from the second aggregation 2 with 34 third instar individuals which were found on a young plant, approximately 25 meters inside a forest, predominated by araucarias. Ethological observations were made in the field for an entire day before the collection of aggregations 1 and 2and during all cage maintenance activities 8: Photographs were obtained both in the field and Caxjas the laboratory Figures Voucher specimens were preserved for all developmental stages except the egg.
The description of morphological features was based on nkde images of living specimens, comparing with the morphology and chaetotaxy from the literature Dias, Nude women of Caxias do sul and Caxias do sulLemaire The measurements were obtained using a digital caliper and a balance, to the nearest one hundredth of a gram.

Monthly collections were made within the Ot from January to Decemberfour nights during each new moon, using light traps as described in Specht et al. Eggs Figure 1ab aCxias large, mean diameter Caxas.
