Aculeate is an enemy from Final Fantasy X-2. A relatively easy enemy to take down. Watch out for its Sleep Needle, and hit it with Water-elemental attacks.
In the Fiend Tale endings, a notable Aculeate was created from the spirit of a Kilika youth who wanted to make a name for himself as a musician. However, he died when his ship was sunk by Sin and lost his mind to the constant buzzing of his wings where it drove him to kill before saved by the Gullwings. Once able to hear his own heartbeat, Aculeate returned to Kilika and finds a youth much like himself. Knowing he could live his dream after what had done as fiend, Aculeate used his buzzing to teach the youth his song before he departed to the Farplane.
