Shaw & Ford (1991)-
Belshaw (1993)Solitary, overwintering as a second-instar larva in the host and pupating in the soil. Hosts: Palaearctic records from Dolyconis spp (mostly D.baccarum), also single questionable records from Holcostethus vennalis and Palomena prasina (all Hemiptera: Pentatomidae). Other records from Pentatomidae and Scutelleridae are probably erroneous. British distribution: S.England (Lizard Peninsula in Cornwall; Hambledon Hill in Dorset/Wilts; Farley in Wilts) and Ireland (Glengariff in Cork). Habitat: English localities are grassland and scrub (Falk, in press). Flight period: July and August (6 records). In Europe June to August (Herting, 1960).
Tschorsnig & Herting (1994)Europe to Scandinavia; NS NW HE RP BW BY NB / A CH. Meadows bushes forest edges. End May to End September (without a distinct peak). Visits flowers; frequent. Dolycoris spp. (Pentatomidae).
JNCC review (1996)DISTRIBUTION Recorded on a number of occasions between 1896 and 1983 at the Lizard Peninsula and Black Head (Cornwall); also from Hambledon Hill (Dorset, 1954) and Farley, Wiltshire (1978). HABITAT Coastal grassland or scrub, and calcareous grassland or scrub. ECOLOGY Reared from a range of widespread and polyphagous Shieldbugs of the genus Dolycoris (Hemiptera, Pentatomidae). Adults in July and August. STATUS The Lizard Peninsula is the stronghold of this species, but its status on the downs of Wilts/Dorset/Hants is very unclear. It is a distinctive species that is unlikely to have been overlooked in the way that many tachinids have been. Status revised from ENDANGERED (Shirt 1987). THREAT Changes in the grazing management, with subsequent alteration of grassland structure through scrub invasion and a reduction in the floristic richness and diversity; the encroachment of agriculture and intensive forestry; the localised effects of recreational pressures such as caravan sites, car parks and trampling at The Lizard. MANAGEMENT Maintain a mosaic of vegetation types using rotational management if necessary, to ensure a rich and varied flora and prevent scrub invasion.
