I want to know the answer to the following question:
Vibrations are used to communicate with members of the same species, and what other species?
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?
Answer: yes
