Pediasia luteella (Denis & Schiffermüller, 1775) Species
Last modified: Dec. 7, 2024, 12:56 p.m.
A very rare and local species in the southern part of Belgium.
It has not been observed for a very long time, but it's still possible it's overlooked due to its similarity with other Crambidae.

Distribution
Imago
Imagos can be confused with darker forms of Agriphila tristella (specimens without whitish longitudinal streaks on forewings) but the earlier flight period 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.
