Fomoria septembrella: mine on Hypericum androsaemum

Hypericum androsaemum, Bergen NH: on this hostplant the mine appears differently


Egg at the leaf underside. The mine begins as a long, winding corridor with a broad frass line that is red brown at first, black brown later. The corridor abruptly widens into a slightly inflated blotch. Here the frass lies concentrated in the centre. Here also a cocoon is made, where pupation takes place. In preparation the larva has cut a semicircular exit slit in the leaf underside, near what later will be the front end of the cocoon.
