6.001 .... B&F 158
Antispila metallella ([Denis & Schiffermüller], 1775)  
Status .....Only discovered new to Nottinghamshire in September 2023, when leaf mines were found at Duke's Wood near Eakring, by Nick and Samantha Brownley. This is predominantly a southern species, but records occur north into Yorkshire. Likely to be somewhat under-recorded, but more widespread in Nottinghamshire and there is potential confusion between one other Antispila species.

The identity of any mine to species level, can be determined by the length of the cut-out at its widest part. Those measuring between 5.0 and 6.5mm are Antispila metallella, while those measuring between 4.0 and 5mm are Antispila petryi. Females of A. metallella make one to three tiny practice slits before actually laying the egg, and these are visible at the start of the mines (if the start is visible in older mines). A. petryi females do not do this. All leaf mines found at Duke's Wood and other sites where the mines have been found, have all been located on those trees growing in shadier conditions and on the older growth.
