Morley’s Final Catalogue: Not listed. Nepticulids were not well studied only 21 species listed.

Recent Status: Recorded in Suffolk.

Life Style: This is a double or triple brooded species and the adults can be found from May until October. The larvae feed on Acer campestre. Larvae will hibernate.

Identification: This species is similar to E. sericopeza. They have a dark wing with white markings, at the base, fascia at one third, a pair of opposing marks on the costa and tornus and pale cilia. The head tuft of E. louisella is a dingy orange compared to a brighter orange for E. sericopeza. The collar is dark for E. louisella and orange for E. sericopeza.
Depending on the time of year the larvae feed either by eating out the centre of leaf or flower buds, causing them to fall, else feeding on the seeds after a narrow gallery mine to reach it. More Info
