Fenusa ulmi Sundevall, 1847
< back | NBN Map ! next >
forms a blotch mine

Food Plant: Ulmus (Elm)

Mine: Early Summer onwards

Notes: A full depth blotch mine, which usually starts from the angle formed by the midrib and a vein. The taxonomy of the sawflies feeding on Ulmus is problematic and unresolved at present. Kaliofenusa pusilla is an unplaced species and F.ulmi was recorded in Ireland (2004, Knight) as K. pusilla.
