Bedankt, ik wacht ook nog op BB wat zei er van zeggen.
Maar denk dat A maculipennis wel goed bij deze past.
Hier het antwoord van BB:
Dear Harry,
Thanks for the enquiry. Unfortunately, it is not so easy... Aphalara is an extremely difficult genus, and there are several species (including maculipennis) that I have not yet seen. In general, you really want to check the genitalia of a male and the distribution of spinules on the forewing to confirm any ids. As far as I can make out, the markings are not quite right for maculipennis, although the wing proportions are. Is the specimen a male or female?
Also, which key are you using? If it is Hodkinson's then you should be aware that there are more species in the Netherlands than in the UK. If you use Ossiannilsson's, then it should be better. I have attached a pdf of Burckhardt & Lauterer's revision of the genus, which you may be able to apply.
Best regards,
Joe
