Hmm...
This doesn't match anything I know about. The frass pattern is highly suggestive of Agromyzidae. It could be that you've found Agromyza alnibetulae, known only from Europe. The only other known birch leaf-mining agromyzid is Agromyza betulae from Japan. Definitely worth looking for more of these this spring!

 
Very cool! If I come across
