Fallovexillum uvacaulis was collected in 2021 by occlupanologist Kurisu at the Yau Ma Tei Fruit Market and Ming Fruit Shop of Hong Kong. Not long after, A. Lee reported similar species in Australia. In all instances it was found preying on bunches of Australian grapes. Only known species collected of the Angulognathoidae (“Like the Angulognathids”) , though other different color morphs have been documented. It should be noted that specimens can be found on ground occasionally due to its loose raptoral stricture, which cause specimens to fall off their prey.
