Account: Rare immigrant from North Africa, appearing in southern England in small numbers. In 1969 at least ten were reported; although the records were spread over eight weeks, the concentration in mid-October appears to have been part of a very large immigration which included other scarce species The far more common Burnished Brass Diachrysia chrysitis has the thorax and abdomen stouter and forewing broader, with basal portion of the metallic patch extending from costa to dorsum; in Slender Burnished Brass most of the forewing is filled by a triangular greenish-brassy area, narrowly bordered at termen, more broadly at costa and dorsum, with pale purplish grey (MBGBI Vol 10). Larva polyphagous, no evidence of breeding in the UK.
