During June of 2000, a small section of the south-facing escarpment of the White Downs in Surrey was searched for the larvae of Cryptocephalus nitidulus Fabricius. After 1-2 hours of searching, seven larval cases were found, four of which were broken and empty. Of the other three larvae, one was very small (≈2mm) and still active. The remaining two larvae were fully grown and the case aperture was sealed in preparation for pupation. These cases were opened and found to contain the cocoon and pupae of hymenopteran parasitoids.
