Genus: Osmia Panzer, 1806
Subgenus: O. (Osmia) Panzer, 1806
Species: Osmia ariadne Peters, 1978
Common name: none
Osmia ariadne have only been described from female specimens. They are black bees with a subtle dark blue-green luster to the thorax and head and a bronze shimmer on the abdomen (Peters 1978). They have primarily black to dark brown hairs on the face, primarily pale hairs on the thorax, and the abdomen has rusty red hair on T1–T3, both black and reddish hairs on T4, and primarily black hairs on T5–T6. Female body length ranges from 11–12 mm (Peters 1978). The name ariadne is derived from the ancient Greek legend Ariadne (Peters 1978).
(modified from Peters 1978)
- Mouthparts much less than the length of the entire body when extended.
- Terga without apical hair bands.
- Female clypeus with tridentate median projection and distinct lateral projections.
- Female scopa reddish-yellow.
May be confused with
The tridentate median projection on the apical rim of the clypeus is distinctive, and it makes Osmia ariadne difficult to confuse with other Osmia species.
Osmia ariadne is native to Greece (Peters 1978). O ariadne specimens have been recorded in Turkey.
