Calybites magnifica (Stainton, 1867)

>

mine

Egg at the underside of the leaf. Here begins a long, lower-surface, strongly branching, epidermal, corridor. After a while deeper layers of tissue are eaten, and the mine develops into a tentiform mine with dispersed frass. Finally the mine is left, and the larva makes on another leaf a marginal roll, almost always folded downwards, which is eaten out from the inside. Thee larva leaves the roll for pupation by biting a round opening. Pupation takes place in a cocoon that is made at the margin usually of the same leaf. The cocoon is yellowish white, strongly shining, 7-9 mm long with a length fold.
