A mine found on Cornelian Cherry at Lynford Aboretum in 2022 is believed to be the first known occurrence in Norfolk. (S. Wright, 27/08/22) New for VC27 also in 2022 at Wymondham (J. Symonds)

A paper by van Nieukerken et al (2018) shows that Antispila treitschkiella feeds on Cornelian Cherry (Cornus mas) and has two generations a year. It has only recently been found in the UK in London (2016).

The Dogwood (Cornus sanguinea) feeding species formerly named Antispila treitschkiella is now named Antispila petryi.
All our former Norfolk Antispila treitschkiella records have now been reassigned to that species.

Forewing costal spot usually trapezoid to almost square.
Best distinguished by male genitalia, larva and hostplant.

Leaf-mine: June to July, August until early November.
Short gallery leading to blotch, larva cutting an oval case.
