Jason Weigner has begun to send me images of Saturniidae (adults and larvae) from Santa Cruz, Bolivia.

Specimens below were taken 20-25km W of Santa Cruz at elevation of approximately 1000m, Santa Cruz Department, Bolivia. Jason resides about 75km E of Santa Cruz.

He has also sent some images from Costa Rica.

Lemaires does not list any of the three very similar Rothschildia species: chiris, orizaba peruviana or aurota speculifera from Santa Cruz Department, Bolivia.

He does not even list R. aurota speculifera in any part of Bolivia. However, the specimen image sent to me by Jason Weigner is most consistent with images I have of R. a. speculifera as compared to the other two species/subspecies: least dentate pm lines on all wings, largest lighter patch near forewing apex, straightest upper third of forewing am line, greatest extension of am line to forewing hyaline area, most distinct black scaling as a diffuse, smooth line (non-dentate, non-undulating) outside white and reddish-pink bands associated with pm lines.

I would expect R. orizaba peruviana to be a brighter orange, and I would expect R. chiris to be darker and at higher elevation.

Regarding the larvae, Jason writes, "Found at about 1000m just west of Santa Cruz, Bolivia, in the Department of Santa Cruz.

"This larva is currently 6cm. Not sure what the food plant is since I found it on the side of a building. There were what appeared to be some sort of Mimosa species near by with bark that almost matched the patterns of the larva but I am not sure if that is the food plant or not. I'll try to raise it, hopefully I have the right food plant."
