Having read a question (and answer) about flies flying, I started to wonder whether flies would really fly with the verb volare. I had always somehow imagined that volare referred to more elegant and graceful flight, such as that of birds or mythological characters, rather than flapping small wings at very high frequency and making a buzzing sound like an insect. I may well have misunderstood the nuance, and the point of this question is to set that straight.
So, which Latin verb(s) do insects fly with in classical Latin? Is volare applicable to them as well, or is some other choice more idiomatic? A quote or two from classical authors would be great. I assume the Romans would mention a fly flying somewhere in the extant literature.
