Distribution:

Following Karsholt & Nieukerken (2010), the species is known throughout Europe except for Portugal, the Tyrrhenian archipelago, parts of the Balkans, Finland and the eastern part of European Russia. Furthermore, A. reaumurella has been found in Serbia and Montenegro (Kurz & Kurz 2010, Kurz & Horvat 2010). In Asia, the species has been recorded from Japan (anonymous 2009a), but is missing in the collection of the Siberian Zoological Museum (Dubatolov 2009). Vertically, the distribution seems to be restricted to a small range from near sea-level to only 700 m a.s.l. (Kurz & Kurz 2010).

A. reaumurella inhabits sunny edges of decidous wood- and bushland and adjacent tall herb vegetation. Here, the males may come together in order to form small swarms of 10 - 20 animals. In a hopping flight, they rise up to one meter above the vegetation, sink down again and rest shortly on the twigs. Then, they repeat their common flight. The imagines are day-active and fly in one generation per year from late April to early June (Kurz & Kurz 2010).

The species is very well characterized among European Adelidae by its bright greenish-golden forewing colouration. Sometimes, Adela cuprella ([Denis & Schiffermüller], 1775) may be somewhat similar, although it always shows a more or less intensive, reddish tinge. The eyes of males are even more enlarged than in A. reaumurella.
