Pupariates on leaf surface; puparium pale yellow, photographed 2 June 05
Reared. Adults photographed 21 June 05. 12 adults and 2 (apparently identical) parastic wasps emerged. 14 exuviae varied from chalky (3) to transparent or greyish, but not obvious which had contained the wasps. Three puparia hadn’t emerged: one of these was brown but otherwise looks identical so is presumably parasitised.
