A glob fly was a Klingon fly, half the size of an Earth mosquito, with no sting, that made a rather irritating buzzing sound.

In 2365, Worf explained his comparison between a glob fly and a Straleb security vessel thusly, indicating that they were similarly bothersome. (TNG: "The Outrageous Okona")

A scene set on Qo'noS in "Point of Light" saw a fly landing on Kol-Sha's entrails. It might be a Glob fly or one of its relatives, although it did not audibly buzz.
