Distribution. In the northern part of Central and West Europe, and the south part of Scandinavia (Gielis 1996, FAZEKAS 2006). The populations from Romania represent until present the eastern limit of the species territory. Biology. The moths fly at dawn and during daytime, from the end of June to September, more specific, the first half of September (Gielis, 1996, Razowski, 1988). The trophic basis is represented by Gentiana pneumonanthe (Beirne 1954, Gozmany 1962, Gozmany 1963, Emmet 1979, Buszko 1986, Gibeaux 1989) and Gentiana cruciata (Gibeaux 1989, Gielis 1996). The eggs are laid in July on buds and flowers. The larvae feed inside the buds, and the hole entrance hole denotes their presence (Gielis 1996). On the host plant one can encoun­ter simultaneously the eggs of Stenoptilia and of Maculinea alcon alcon or M. alcon xe­­rophila. The caterpillars develop during July-August. Pupal period is about two weeks (Fig.8) (Gielis, 1996). Larvae pupate usually on the host plant’s stem or the back leaf (Fig.9). References Gielis C. 1996. Pterophoridae. In P. Huemer, O.
