Since one of the three references (Arist.HA551a14, Thphr.HP2.4.4, Plu. 2.636c) is in Aristotle's Historia Animalium, I'm kind of assuming it's an actual insect. But if you can track down the texts, I'd appreciate getting more information.
I had tried but couldn't find the texts. All I found were translations of Aristotle's Historia Animalium (http://classics.mit.edu/Aristotle/histo ... .4.iv.html and http://classics.mit.edu/Aristotle/history_anim.5.v.html), both of which seem to indicate that it is anyone's guess.
