|JNCC review (1996)||DISTRIBUTION South East England and East Anglia (Sussex, Kent, Essex, Herts, Berks, Oxford, Bucks, Suffolk, Norfolk, Cambridge, Hunts).
HABITAT Grassland and woodland, and also in gardens.
ECOLOGY The larvae are parasitoids of caterpillars of the locally common moth Orthopygia glaucinalis (Lepidoptera, Pyralidae) which lives saprophagously in a wide range of decaying vegetable matter such as haystacks, thatch, nests and dreys, etc. Adults from May to September.
STATUS About a dozen widely-scattered post-1960 localities, though possibly still under-recorded. It can occur regularly, though sparsely, in gardens.
THREAT Conversion of sites to intensive agriculture or forestry; changes in the grazing management of grassland, leading to scrub invasion and a loss of floristic richness and diversity within sites.
MANAGEMENT Maintain sites in a natural state with a range of vegetation types, using rotational grazing management on grassland if necessary and maintaining open rides and clearings in woods, ensuring a wide range of trees, shrubs and herbs.|
