Coelioxys lanceolatus
Local name: lansettkägelbi
The lansettkägelbi (Coelioxys lanceolatus) is a distinctive cuckoo bee species characterized by its pointed, lance-like abdomen and metallic sheen. As a kleptoparasitic bee, it does not collect pollen itself but instead lays its eggs in the nests of other solitary bee species, where its larvae consume the host's provisions.

Species Profile
The lansettkägelbi (Coelioxys lanceolatus) is a distinctive cuckoo bee species characterized by its pointed, lance-like abdomen and metallic sheen. As a kleptoparasitic bee, it does not collect pollen itself but instead lays its eggs in the nests of other solitary bee species, where its larvae consume the host's provisions.
Coelioxys lanceolatus, a cuckoo bee species, faces severe population declines primarily due to habitat loss and degradation of the specialized nesting sites required by its host bee species. The species is particularly vulnerable because it depends entirely on specific host bees for reproduction, making it susceptible to any factors that negatively impact host populations.
Key Facts
Habitat & Distribution
Lansettkägelbi inhabits areas with abundant wild flowering plants and suitable nesting sites for its host bees, including forest edges, traditional hay meadows, and extensively managed grasslands. The species requires proximity to sandy or loamy soils where host bees construct their ground nests, as well as diverse floral resources that support the broader solitary bee community.
