15.006 Caloptilia rufipennella (Hübner, 1796)
< back | map | next >
cones formed at the leaf edge

Food Plant: Acer pseudoplatanus (Sycamore) Elsewhere: also on Acer campestre (Field Maple), Acer platanoides (Norway Maple), Acer saccharinum (Sliver Maple)

Egg: Underside of leaf, usually near midrib

Mine: June-July; August-September

Pupa: In a yellowish cocoon on underside of leaf

Notes: At first in a very small triangular whitish blotch in the angle between veins. Then forms three progressively larger cones at the tip of a leaf lobe; sometimes all in the same leaf. Caloptilia honoratella (recently discovered in the Uk) makes similar mines in late summer and so the moths must be bred to identify.

National Status: Common

Bradley No: 284

Data: 07.vii.2002, Fleet, Hants, VC12
