Thank-you Dr S (PhD et al), for your recent, though rather abrupt-sounding and profoundly discourteous communication, but yes, I do happen to know all about the “Fly” rule….The one that states that if an insect is a true fly, such as a House-Fly, Snipe-Fly, Hover-Fly or Trouser-Fly, then the “fly” part is hyphenated or made altogether separate, but that if it’s not a proper fly, then the “fly” part is included in the rest of the name, such as Damselfly, Dragonfly, Butterfly or Mayfly….The trouble is, Dr S (PhD et al), I’m just not anally-obsessive enough to feel even the remotest of needs to get it absolutely right every single time!
