Molipteryx fuliginosa (Uhler, 1860) (Heteroptera, Coreidae) in the V. L. Komarov Ussuriysky State Nature Reserve and adjacent territory (Russian Far East)

The article presents a comprehensive overview of the distribution of Molipteryx fuliginosa (Uhler, 1860) (Heteroptera, Coreidae) within the V. L. Komarov Ussuriysky State Nature Reserve and its surrounding areas in the Russian Far East. The findings are based on field collections conducted by the authors between 2015 and 2024, supplemented by continuous observations since 1998. The colonization intensity of various habitats was assessed through the presence of overwintered adults at the onset of the growing season, mating pairs, and larvae of different instars. Results indicate that M. fuliginosa predominantly inhabits ecotones and illuminated areas, such as forest roads, clearings, and areas around ranger stations, while being absent in densely forested regions. The species shows a preference for mesophilic plant associations with moderate insolation. Additionally, we report Angelica dahurica (Apiaceae), Adenocaulon himalaicus, Cirsium maacki, Synurus deltoides (Asteraceae), and Maackia amurensis (Fabaceae) as newly documented host plants for M. fuliginosa.
