Some species use vibrations for communicating within members of the same species, such as to attract mates as in the songs of the shield bug Nezara viridula. 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. The Madagascar hissing cockroach has the ability to press air through its spiracles to make a hissing noise as a sign of aggression; the Death's-head Hawkmoth makes a squeaking noise by forcing air out of their pharynx when agitated, which may also reduce aggressive worker honey bee behavior when the two are in close proximity.

Living in association with ants is called what?
Answer: myrmecophilous

In 1744, Burke started at Trinity College Dublin, a Protestant establishment, which up until 1793, did not permit Catholics to take degrees. In 1747, he set up a debating society, "Edmund Burke's Club", which, in 1770, merged with TCD's Historical Club to form the College Historical Society; it is the oldest undergraduate society in the world. The minutes of the meetings of Burke's Club remain in the collection of the Historical Society. Burke graduated from Trinity in 1748. Burke's father wanted him to read Law, and with this in mind he went to London in 1750, where he entered the Middle Temple, before soon giving up legal study to travel in Continental Europe. After eschewing the Law, he pursued a livelihood through writing.

What club did Edmund Burke's debate club merge with in 1770?
