Rhyssella obliterata
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Rhyssella obliterata faces significant pressure from deforestation and habitat fragmentation across its limited range in temperate and boreal forests. As a parasitoid wasp that depends on specific host wood-boring beetles, the species is particularly vulnerable to logging practices that remove dead and dying trees essential for its reproductive cycle. Climate change poses an additional threat by altering forest composition and potentially disrupting the synchronization between this wasp and its beetle hosts.
Habitat
Rhyssella obliterata inhabits mature coniferous and mixed forests, particularly those with abundant dead and decaying wood. The species requires forests with sufficient populations of wood-boring beetle larvae, which serve as hosts for its parasitoid lifestyle.
