A very rare and local species in the southern part of Belgium.
Not observed for a very long time, but it's still possible it's overlooked due to the similarity with other Crambidae.
Imago's can confused with darker forms of Agriphila tristella (specimens without whitish longitudinal streaks on forewings) but the earlier flightperiod can be a hint to be vigilant. Also Pediasia luteella has brownish-yellow to dirty-white antennae in contrast to the pearly white antennae of Agriphila tristella .
Male genitalia are indistinguishable from Pediasia fascelinella.
Larvae can be found from September till May.
The larva lives in a silken gallery amongst roots of different grasses and hibernates.
Imago's are on the wing from late May towards early August.
Open grassy habitats.
