Abstract Oceanic islands, recognised for their isolation, high endemic species richness and unique evolutionary paths compared with continental counterparts, are extremely susceptible to anthropogenic activities. The fragmentation of island habitats disruption native ecosystems has increased the risk extinction many species, including arthropods. Extinction is not random, some traits may increase probability entering an trajectory. Studying alongside International Union Conservation Nature (IUCN) threat levels offer valuable insights into vulnerability inform targeted conservation strategies. Here, we aim test predictability IUCN categories status based on Azorean arthropods' functional traits: body size, trophic group vertical strata occupancy. We demonstrate that limited occupancy, particularly those restricted ground level, more vulnerable than inhabit forest canopy. Contrary our expectations, size did appear be direct predictors level. Overall, findings underscore previous ongoing effects human activities in ecosystems. Hence, emphasise need look at as future extinctions
