The Science Behind Butterfly Vision : Short Wave Adriana Briscoe, a professor of biology and ecology at UC Irvine, studies vision in butterflies. As part of her research, she's trained them to detect light of a certain color. She also explains why they bask in the sunlight, and why some of them have 'hearts' in their wings. Plus, you'll never guess where their photoreceptors are.

She's written about the importance of teachers and mentors in diversifying the STEM fields.

Adriana Briscoe, a professor of biology and ecology at UC Irvine, studies vision in butterflies. Turns out, butterflies are really cool. For instance, they can be trained to detect light of a certain color — which she's done as part of her research.

Adriana also answers questions you might've never thought to ask like: Why they bask in the sunlight? And why do some of them have 'hearts' in their wings?

Plus, you'll never guess where their photoreceptors are.

We also discuss the importance of teachers and mentors in diversifying the STEM fields, which Adriana has written about.
