Egg: Underside of leaf

Mine: June - August

Notes: An initial gallery, which usually follows the leaf margin. Then forms a blotch, mining from the leaf base to the tip (as shown). The larva is pale yellow, with a pale brown head. Moths reared to confirm identity. The presence of a pupa in the mine is unusual for this species and may indicate parasitism. Mine found on Lotus pendunculatus (Greater bird's-foot Trefoil). The mine is similar to that formed by T.eurema.
