Hello,

Just wanting to be sure, but I'm pretty certain this must be Liriomyza graminivora. And in that case a species new to the Danish fauna.

Single specimen caught in malaise trap during the second week of June 2021 at a birch forest location on reclaimed land near Copenhagen.

All the very best Smile

Agromyzidae: Liriomyza graminivora Hering, 1949: If you identified your specimen after V.V. Zlobin (2003) Dipterological Research 13 (2002)(3): 145-178 and L. Papp & M. Černý (2017): Agromyzidae (Diptera) of Hungary. Vol. 3, the identification should be correct. Femora should be more or less yellow (femora basally slightly dark occurs), vte and vti bristles should grow on yellow background and a narrow yellow band in front of scutellum combining the pair of distinct yellow patches behind the inner postalar setae should be present. As the species is known from the UK, Belgium, Germany, Poland, Lithuania and European Russia, Denmark is a filled geographical gap. Further confirmed countries of distribution are Czech Republic, Hungary, Romania, Slovakia, Switzerland, Spain and Uzbekistan.

Thanks! I identified it using L. Papp & M. Černý (2017). The specimen corresponds closely to the description given by you.
Denmark represents unfortunately a geographical gap when it comes to many Diptera of the less conspicuous kind.
