A rather large, yellowish brown blotch mine with fine concentric grey-green arcs on the upperside of a leaf. Already in a rather young stage, the caterpillar constructs a semi-circular pupation chamber in which it rests and presumably also moults. The last instar larva detaches this pupation chamber leaving a circular space in the upper cuticula. The frass is ejected from the mine.

The egg is deposited on the upperside of a leaf.
In contrast with the other Tischeria species, the last instar larva of T. decidua detaches the semi-circular pupation chamber from the upper cuticula of the leaf and drops with it to the ground. The species hibernates in the larval stage and pupates in early spring.
