Comments-
Shaw & Ford (1991)-
Belshaw (1993)Female abdomen and reproductive strategy similar to Compsilura concinnata (see below). Immature stages and biology in Dowden (1933). Overwinters in the peritrophic membrane of the mid-gut of the host, usually as a second-instar larva. Usually emerges from the host to pupate in the soil. Hosts: a wide range of Lepidoptera and (more rarely) sawfly larvae (Hymenop. tera: Symphyta). Rarely attacking hairy caterpillars (Dowden, 1933). No British host records. British distribution: England, Wales and Ireland (near Flagstaff in Louth). Habitat: woodland (Emden, 1954). Flight period: late May tc late August (at least 50 records). In Germany peaking May and late July/early August (Tschorsnig, 1989).

Shaw & Ford (2000)Thaumetopoea pinivora (Treitschke): 1 male 1 female ex pupae 31.vii.93 vi.94 also 2 females viii.93 20.viii.95 (!) SWEDEN [-land] (CE); Lacanobia suasa (Denis & Schifferm¦ller): 1 female ex larva 2.ix.93 p.l.e. 27.ix.93 (died unemerged) Beeley Moor Derbyshire (THF); Dryobotodes eremita (Fabricius) on Quercus mas: 1 male 1 female ex prepupae 15.v.96 1.vi.96 16.vi.96 FRANCE [Bernac Lot-et-Garonne] (MRS). The record from L. suasa appears to be the only British rearing record of B. nigripes from any host but it has been recorded from the same host from Magdeburg (Ziegler 1983).
