In older literature this species has been referred to as Chrysis osmiae Thomson. Identification keys and general biology are given in Morgan (1984), Falk (1991) and Kunz (1994).
Scotland only: Morayshire (Aviemore, Loch Garten), East Perth (Blair Atholl) and Wigtownshire (Whithorn). Very rarely seen.
Overseas: Fennoscandia, central Europe and the Pyrenees, Poland, north China, Korea, Japan.
Listed as Vulnerable (RDB2) by Shirt (1987) and provisionally downgraded to Rare (RDB3) by Falk (1991).
Occurs in three habitats related to its three possible hosts. Blair Atholl (Osmia inermis) - upland, base-rich grassland. Loch Garten (O. uncinata) – mature Caledonian pine woodlands. Whithorn (O. parietina) - probably traditionally-managed upland pasture with old stone walls and rocky outcrops (Else & Edwards 1996).
Probably a minimum two-year life-cycle. From the few available records, adults fly from May to July.
