The Batia lambdella is a small moth of the Oecophoridae family with a wingspan of 11-17 mm.
Batia lambdella in Europe is absent from the Scandinavian peninsula, the Baltic countries, Belarus, Russia, Croatia and Bulgaria. In Italy it is also present in the islands. *
The front wings of the Batia lambdella are of a dark orange / ocher color, slightly darker on the tips and in the thick fringe that surrounds them. At the border between the light and dark parts there is a broad brown-black line interrupted through the front wings, the dorsal part forms a continuous pointed pattern, when the wings are relaxed while the moth rests. ***
The hind wings are translucent brown / ocher, strongly fringed. The head is black, the thorax dark orange / ocher, the abdomen brown / ocher. Similar to the congener Batia lunaris , it is about 50% larger than the latter.
