Egg: On leaf-stalk in summer; on samara in spring (shown to the left of the seed)

Mine: June, September - May

Notes: In June mines the wing of a samara, mining into the seed with a short gallery. The cocoon is formed on the samara (as shown), which often falls to the ground. The second generation mine the petiole initially then the flower bud and forms a cocoon on this. Both generations may form cocoons on the tree trunk.
