Like other members of the family, this species has functional jaws and it feeds as an adult on pollen grains from a wide variety of flowers including those of hawthorn, Cytisus, Lychnis, pine, Plantago, rose, nettle and Veronica as well as numerous grasses.

The females are similar to Micropterix calthella but has the whole base of the forewing purple, compared with M. calthella which has a purple patch on the base of the costa. In Britain both species can be found, during the day, on creeping buttercup, but the UKmoths website recommends searching the lower flowers of hawthorn Crataegus monogyna for M. aruncella.;Larva
The larva feeds on detritus at the base of herbaceous plants before pupating in a tough cocoon.
