DescriptionDistributionGentiana cruciata is widespread in most of Europe (except Portugal, Great Britain and Scandinavia) and in Western Asia.[4]HabitatThis plant prefers dry calcareous soil in forest edges, bushy slopes, pastures, grasslands and dry meadows, at an altitude of {{convert|200|-|1600|m}} above sea level.[3] Host for Phengaris rebeliPhengaris rebeli is an endangered butterfly which feeds upon G. cruciata.[5] Female P. rebeli lay their eggs on the upper side of G. cruciata leaves and three to four weeks later, the P. rebeli larvae emerge and begin to feed on the seeds and flowers of this grassland plant.[5] After the P. rebeli reaches its fourth larval instar, it drops to the ground to be picked up by Myrmica schencki ants and brought to their nests.[5]Female P. rebeli prefer to lay eggs on G. cruciata growing in clumps rather than individual plants, and on the taller plants, as they are less shaded and allow the eggs to grow and develop faster.[5] GalleryReferences1. ^[https://www.biolib.cz/en/taxon/id40570/ Biolib] 2. ^USDA 3. ^1 2 3 Pignatti S. - Flora d'Italia – Edagricole – 1982.
