Egg: underside of leaf

Notes: Forms a long, relatively wide mine (a developing mine is shown). The larva is yellow, with a brown head. The frass is initially in a thin central line, but later may vary from a thin central line to frass almost filling the mine. The moth was bred (and gen det) to confirm identity. An uncommon, but widely spread leaf miner.
