295 Caloptilia hauderi (Rebel, 1906)
< back | map | next >

 

Food Plant: Acer campestre (Field Maple), Acer pseudoplatanus (Sycamore)

Egg: underside of leaf

Mine: June

Notes: In the UK it is now know to be the spring generation of C.semifascia. It makes a small blotch initially, usually in the angle formed by the midrib of the leaf and a vein. The parenchyma is eaten giving the blotch a speckled appearance. Makes three cones (compare with C.semifascia on the same tree where the cones are cylindrical and have sealed ends). The cones of C.hauderi are made up to a month before those of C.semifascia. An uncommon Southern species, which seems to be expanding its range.
