I've moved this to arthropods for you.
Where you know the species as in this case, please can you look up & add the scientific name so that we can take this off of the "unknown" list. Because we have a global user base & sometimes many different common names for the same species, the system uses the scientific name to link similar spottings - which also means this may come up in the thumbnails on other spottings & more people may take a look & favorite it. Without the scientific name this will continue to show up as unidentified & you may get further ID suggestions from other users.
