Morley’s Final Catalogue: Ipswich, bred in 1934 (Whit.); Blaxhall among broom (Hkr); Aldeburgh and Southwold (Ctw); Gorleston pales (Mly); Brandon.
Recent Status: Recorded a little less frequently than L. laburnella.
Life Style: This is a single brooded species that can be found during June and July and so flies later than the earliest of L. laburnella. The larvae mine the surface of stems of Cytisus scoparius and Genista tinctoria. They pupate in a white cocoon on the stem of the foodplant.
Identification: Two species of Leucoptera found in Suffolk are very similar. L. laburnella and L. spartifoliella both have white fore- and hind-wings. The keyable difference is that L. spartifoliella has yellow/ochreous scales along the complete proximal edge of the metallic tornal spot and the first costal stria is distinctly wedge shaped. In L. laburnella the yellow/ochre scales are only along the top edge and the stria is almost parallel sided. This is not necessarily easily seen. Genitalia dissection shows clear differences between the two species. The larvae of L. spartifoliella are far less readily spotted than those of L. laburnella. They mine upwards and the ovum does not remain attached, which facts separate them from Trifurcula immundella. More Info
