Researchers in Spain have shown a novel way for insects to travel—as larval stowaways in the guts of migrating birds.

He and a colleague examined droppings in a salt marsh roosting site of waterbirds called black-tailed godwits. The birds were feeding by the thousands on their way from northern breeding grounds to their winter homes in Africa.
