In the long-closed thread, The Right of a Fly to a Common Name, the question was asked,
Who has the right to create common names outside of iNaturalist and how is this right bestowed upon them?
And the answer was given,
However, if you want to invent a common name and try to have it meme its way into public consciousness and usage…go for it, but it would be the process of years, if not decades or generations, just to be sure it was actually accepted.
Well, this may be the case for a common name in the strict sense, i.e. a name in common use; however, in ornithology, at least, every newly-discovered bird seems to come with a “common” name as well as a scientific one. For instance, in this article, 10 New Birds Described in Biggest Avian Discovery in More Than a Century, they were only discovered and described last year, in 2020, but you will note that every one of them is referred to by a “common” name, such as Taliabu Grasshopper-Warbler and Peleng Leaf-Warbler. No way have those names been long-established in common use.
I know of at least one botanical publication, Madroño, in which new species descriptions often include a proposed common name, which the describer gets to assign.
So you’d think it would be a simple matter of using the name in a scientific publication. However, for insects, this does not seem to be accepted; entomological publications actively discourage using common names, especially for insects that do not already have an established one.
So my quandary is, if there is a certain species of fly, which I have consistently thought of as jester fly because of its motley colors and jaunty mannerisms (and that is how always I referred to it in my field journal since I did not know its taxon), how do I go about putting that name out there to see if it sticks?
