Description of adults: Examined: 6 , 3 . Forewing length: 4.7-5.2 mm; 4.7-5.0 mm. Vestiture of hair-like scales on the head mixed black and light yellow; face smoothly scaled, metallic bronzy golden; eyes dark brown, about 0.3 mm in diameter; distance of eyes (frontally) about 0.55 mm; palpi directed ahead, about 0.5 mm long, golden shining, ventrally with single distant, long black bristles; proboscis bronzy golden basally; antennae in about 2 1/2 of forewing length, purple violet at basis, distally ringed white and dark violett, distalmost white; antennae in about 1 1/4 of forewing length, basally slightly thickened by erect scales, dark purple violet, distally white; thorax and tegulae bronzy golden shining, tegulae partly aslo purple; forewing bronzy golden at basis, otherwise reddish golden to brown golden, distally bronzy golden sprinkled and with more or less violet shimmer; at 1/2 a narrow, straight white cross-fascia across the whole wing width, bordered at both sides with dark violet; at 3/4 a more or less distinct, small white costal spot; fringe reddish golden to purple violet; hindwing completely covered with broad scales, grey-brown with violet shimmer; fringe reddish to bronzy golden; underside grey-brown with intensive coppery, on hindwing more violet glance, cross-fascia of forewing only weakly shimmering through; fringe like on upperside; underside of thorax metallic greenish-golden shining; legs also metallic greenish-golden shining, tibiae and tarsi purple violet outside, except for a greenish-golden distal ring on each segment; foretibia with epiphysis; midtibia with a pair of spurs at distal end; hindtibia with a pair of spurs each at about 0.5 of tibial length and at distal end; abdomen bronzy golden with coppery to violet shimmer; in , segment margins 1-6 ventrally conspiciously whitish golden, distal part of abdomen flattened dorso-ventrally; in , segment margins less conspiciously whitish golden.

Variability: In specimens from Italy, the ground colour is more brownish, whereas in specimens from Greece and Cyprus, the forewings have a more purple-violet shimmer.

Distribution:

The species is known from the central and eastern Mediterranean region. It has been recorded so far from the Tyrrhenian archipelago, Tuscany, Greece (including the Peloponnesos, Crete, Rhodes and Lindos) and Cyprus and is known also from Romania (Mann 1871, Karsholt & Nieukerken 2013). Vertically, records are available from near sea-level up to about 440 m a.s.l. only (Kurz & Kurz 2015).

The species inhabits dry and warm habitats, like open bushland, open macchia, bramble-scrups, sunny wood edges, clear cuttings and tall herb vegetation. Here, the animals fly during daytime in the sun, preferably in the late morning. Single animals however, have been observed as late as 17:00. Within this time also nectar is taken up, whereas a single copula has been observed in the afternoon only (between 15:00 and 16:00). Males frequently swarm together around blossoming shrubs. Nectar-uptake has been observed on open blossom, where the animals can sit during sucking (Kurz & Kurz 2015). The following plants habe been documented to serve as nectar sources: Erica arborea (Zeller 1850), Cistus creticus and Rubus sanctus (Kurz & Kurz 2015). The flighttime of the species depends on the altitude and may vary from late March till June in one generation.

Among European Adelinae, the species is characterized very well by its wing markings, especially by the small white costal spot at 3/4, which is nearly always present. Only Adela albicinctella Mann, 1852 has a similar spot on the costal margin, but this species is distinctly larger, darker violet in ground colour and distributed allopatrically in the Alps and the central European uplands.
