Adrea, a recent PhD graduate from UCLA, is mentoring three students in the NAPIRE program with projects on Ithomiin butterflies—a diverse group of clear-winged, neotropical butterflies that form breeding aggregations and tend to roost together.  One of Adrea’s students, Katie, is investigating predation risk of roosting butterflies using models of two species that she’s constructed. Here, Katie checks her model butterflies for damage inflicted by predation attempts on the models.
