Nomada arrogans
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Nomada arrogans faces severe population declines primarily due to the loss of its specialized host bee species and degradation of flower-rich grassland habitats. Agricultural intensification and urban development have fragmented the sandy soils and diverse flowering plant communities essential for both this cuckoo bee and its hosts. Climate change further threatens the delicate timing synchronization required between Nomada arrogans emergence and its host species' nesting cycles.
Habitat
Nomada arrogans inhabits flower-rich grasslands, heathlands, and sandy coastal areas where its host bee species nest in exposed soil. This cuckoo bee requires diverse flowering plant communities that bloom in sequence to support both adult feeding and the reproductive cycles of its specialized hosts.
