Diagnosis
Length 2–4 mm.
The species differs from other species of Hedychridium by its smaller size and almost completely green or bluish body, which occasionally has weak golden reflections dorsally on the mesosoma. The tarsi are pale brown. Exceptionally small and greenish males of H. ardens can resemble H. zelleri, but they have sparser and coarser punctation dorsally on the mesosoma.
Distribution
Finland. Rare.
West Palearctic: northern and central Europe (Linsenmaier 1959).
Biology
Habitat: sparsely vegetated sandy areas, usually near seashore. Adults are occasionally found on flowers.
