Rainbow qaana
From Wookieepedia, the Star Wars wiki.
Rainbow qaana were a species of insects that were bred and used by the Yuuzhan Vong. They were kept for the ethereal music that they produced when clicking their mandibles together and were only used in special ceremonies, or in the presence of the Supreme Overlord.
It is unknown what became of the qaana after the war ended; though it can be assumed they were transplanted to Zonama Sekot where they would have joined the tampasi.
