I want to know the answer to the following question:
What is a lycaenid caterpillar?
All the background I'm provided with is that "Vibrations can also be used to communicate between entirely different species; lycaenid (gossamer-winged butterfly) caterpillars which are myrmecophilous (living in a mutualistic association with ants) communicate with ants in this way.". Is that enough to answer the question?
