Leaf Miner Fly Babies Scribble All Over Your Salad

Season 8 Episode 7 | 4m 25s | CC

This fly’s larvae tunnel inside bitter-tasting greens like arugula and kale, leaving squiggly marks behind. The plants fight back with toxic chemicals. So before laying her eggs, the fly mom digs into a leaf and slurps its sap – a taste test to find the least toxic spot for her offspring.
