Food Plant: Sorbus aucuparia (Rowan)

Egg: Underside of leaf

Mine: July - August

Notes: A long thin linear gallery with frass in a thin line, sometimes broken. This distinguishes it from S.nylandriella, which never has linear frass throughout the mine. The gallery of S.magadalenae is also narrower than S.nylandriella. S. magdalenae can both be an edge miner or make a small mine in the leafblade (as shown), or run along a vein. The larva is green.
