663 Dioryctria fusca, Haw., the Brown Knot-horn, a sparse species, flew to Stowmarket light, 22.viii.1959. 682 Euzophera neophanes Durr., the Daldinia Knot-horn, seems only to have been taken in in Suffolk once before 25th August, 1959, when a fine specimen flew to light at Thelnetham Fen. The larva feeds on globular black fungus (Daldinia) that grows on dead stems of gorse and birch. Consequently the moth is found where there has been a fire, as in the case of Thelnetham and possibly as at Shipmeadow before 1935. It is very local in Britain generally, Suffolk being its Northern limit, and this is the third occasion on which it has been found near a marsh. 694 Galleria mellonella L. (cereana, L.). Formerly a serious pest in hives before modern improvements, this, the Honeycomb, is now very rare, particularly in Suffolk where 1 cannot find a record later than 1919.

LEPIDOPTERA REARING 1959-60. by
(Apatura iris, L.). In August, 1959, two ova were found on sallow in a wood in Suffolk. T h e resulting larvae were kept on cut twigs of sallow for a few weeks and were then transferred to a small sallow sapling growing in the garden. They were protected from predators by netting. In previous years larvae have started to hibernate in October, but this year, no doubt owing to the continuing hot weather one of the two larvae continued to feed and grow. On lOth October it moulted for the last time. On 19th October, as the weather turned much colder, the larva was brought indoors, where it continued to feed. It pupated on 6th November, and a male, rather smaller than usual, emergedonöth December. The second larva hibernated in the normal manner, started to eat again at the beginning of April, 1960, and resulted in a male emerging on 20th June. PURPLE EMPEROR
