Rhyssa amoena
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Rhyssa amoena faces significant pressure from deforestation and habitat fragmentation across its range, as this parasitoid wasp depends on mature forest ecosystems that support its wood-boring beetle hosts. Climate change poses an additional threat by altering the phenology of both the wasp and its host species, potentially disrupting the precise timing required for successful parasitism. Agricultural expansion and logging activities continue to reduce the availability of suitable dead and dying trees that serve as breeding sites for both R. amoena and its prey species.
Habitat
Rhyssa amoena inhabits mature coniferous and mixed forests where it parasitizes wood-boring beetle larvae, particularly those in the family Siricidae. The species requires forests with abundant dead and dying trees that provide breeding sites for its host species, typically found in temperate forest ecosystems across its range.
