Wingspan 6 - 8mm. There are five fairly similar species in this genus, M. aruncella being the most common. The wings are metallic gold. The male has a complete central white band with an incomplete white band before and after it.
A wide variety of habitats are used, the moths being unusual in having functional mandibles and can feed on pollen, often in Hawthorns or buttercup species. The larvae are believed to feed at the bases of herbaceous plants, or possibly fungal hyphae in the leaf litter.
