Since a pygmy leaf-mining moth larvae feed on leaves, creating a lure with the leaves of their host plants could serve as a suitable trap food to attract them.

The eggs of a pygmy leaf-mining moth are typically laid on the undersides of leaves, often in the proximity of leaf veins. During the larval phase, a pygmy leaf-mining moth caterpillars can be found inside the leaves themselves, evident as miners creating visible trails or blotches. These caterpillars are best sought by examining the leaves for mining patterns. Pupation commonly occurs in a cocoon attached to a leaf or concealed in leaf litter on the ground.

The best time to find adult a pygmy leaf-mining moth would most likely be during their flight time, typically around dusk or dawn when many moths are most active. Larval stages would be present during the growing season of their host plants.

A pygmy leaf-mining moth are more likely to be found in mild weather conditions, without extreme heat, cold, or rain, as these conditions are most conducive to their activity and survival.
