Beautiful botflies, luscious leeches, and the wonder of parasites

Dino Martins has plucked maggots out of a dead elephant, pulled botflies out of camel snot, and willingly let a horsefly feast on him. Why? Because he’s obsessed with parasites.

Dino is an entomologist who grew up in rural Kenya, and he’s worked all over the world studying how insects keep this planet alive. And along the way, he met some of the world’s most iconic freeloaders, which he describes in his new book, “Hidden Creatures: Luscious Leeches, Bashful Botflies, and the Wondrous, History-Shaping World of Parasites.”

Flora speaks with Dino about his unlikely journey into science, the beauty and disgust of parasites, and why these little moochers deserve more of our care.
