Zeller (in litt.) has found the species on a dry, grassy slope at the edge of bushes. The imagines are on the wing in May and early June (Kurz & Kurz 2011).

Stages in development:

The early stages are unknown.

Eventually, the species may be mixed up with specimens of Micropterix calthella Linné, 1761, having purple spots on the forewings. Such specimens are frequently found in the northern Apennines, but always they lack the silvery white markings. Another similar species is Micropterix sicanella Zeller, 1847, which may be distinguishable with certainty only by examination of the male genitalia. Nevertheless, to present knownledge the distribution ranges of M. emiliensis and M. sicanella do not overlap.
