The parasitoid Chorebus rostratae is added to the British list
Three (1♂, 2♀) C. rostratae Griffiths, 1984 (Braconidae: Alysiinae: Dacnusini) were reared from the puparia of Phytomyza rostrata Hering, 1934 which were obtained from the stems of Yellow-rattle (Rhinanthus) at Far Ings National Nature Reserve, Barton, North Lincolnshire (VC54), representing the first record of this parasitic wasp in Great Britain.
The article* illustrates the wasp and discusses two other parasitoids which were also reared from P. rostrata.
