Dear bugman,
I saw this bug at home yesterday for the first time ever, and I have no idea what it is. I hope you can help me identify it! I’m in Argentina and fall is just starting here. It’s been very humid and rainy for the past couple of weeks.

Dear Mercedes,
This sure looks like a North American Ailanthus Webworm Moth,
Atteva aurea, to us.  Based on this Zoo Keys article, we believe your species is Atteva pustulella.  According to Eco Registros, the latter species is found in Argentina.
