Glyphipterix thrasonella is a species of moth of the family Glyphipterigidae. It is found in the western part of the Palaearctic realm. The wingspan is 11–15 mm.The forewings are shining bronzy, sometimes coppery-tinged ; six obscure golden metallic transverse streaks from costa between 1/3 and apex, and one or two from dorsum posteriorly, all sometimes obsolete ; a violet -black mark on tornus, enclosing two or three golden metallic dots, and a similar dot above it ; sometimes two or three fine black dashes above this ; a blackish apical spot ; dark line of cilia indented below apex. Hindwings are dark fuscous. Adults are on wing from May to August. The larvae probably feed on Juncus species.

Glyphipterix simpliciella has a wingspan of 6–9 mm. and can reach a length of 3–4 mm. These tiny cryptic moths have dark brown forewings with a slightly metallic sheen. They also show a black apical spot and five white or silvery streaks along their costa, two across the dorsum and one in the posterior corner of the wings. The hindwings are dark grey, with grey cilia. Both sexes are similar. This species is rather similar to Glyphipterix equitella and Glyphipterix schoenicolella.

The wings are brown mottled with white spots and measure about 12 mm across. High individual variation in wing pattern can make the leek moth difficult to distinguish from other Acrolepiopsis species at first, but its distinct genitalia make it easily identifiable. Males of this species can be identified by their long saccus, a portion of the male genitalia used for grasping females, and females by their long and flat ductus bursae, a portion of the female reproductive tract.
