s, which they lure by waving their antennae and making prey-like movements. The larvae can often evade the first strike of the amphibian by being alert, and then strike back at once, while the amphibian is in close proximity. Latching on with their mandibles, they suck the body fluids of their new host, progressing to chewing its skin and eating its tissues. Eventually they may kill their host. Even if they are taken into the amphibian's mouth at the first strike, they may survive; one young frog appeared to find the larva it caught distasteful, failed to spit it out, swallowed it, only to regurgitate it a couple of hours later, covered with
