The larva initially creates a narrow gallery from an ovum on the underside of a leaf. They head towards the leaf base. They then create a large blotch placing the frass towards the leaf base. The mine is similar to that of T. eurema and must be reared to the moth for identification. T. eurema adult moths have clear pale opposing tornal and opposite costal spots or a fascia. More Info
