New for Norfolk in 2020 when a large female moth with wingspan of 21mm, well outside of the stated size range, was caught in a Dereham garden by David Norgate (05/07/2020, Gen. Det. Female - D. Appleton)

One of three very similar rare Coleophora that are virtually impossible to identify without recourse to dissection, size (wingspan) should be used as a guide only:
C. vibicigerella 10.5-14mm (No Norfolk records)
C. conspicuella 13-17.5mm
C. vibicella 17-22mm (No Norfolk records)

As the first for Norfolk example shows, size is not reliable for determination, gen. det. required.

Determination by Genitalia Examination Required

Case: A good quality photo or specimen of the case and plant/pabulum is required.
