So far, the species is only known from the Langbian Plateau, in southern Vietnam.
Although males almost certainly call to attract females to suitable tree-holes, their advertisement call has yet to be documented.
Rhacophorus vampyrus is a phytotelm (tree-hole) breeder, depositing eggs in foam nests in small tree-holes. The species is named after its unusual, ‘fanged’ tadpoles.
Given the available information, we suggest the species should be considered Data Deficient following IUCN’s Red List categories.
