The light blue butterfly ant ( Phengaris teleius , syn .: Maculinea teleius , Glaucopsyche teleius ) is a butterfly ( butterfly ) from the family of the bluebells (Lycaenidae). The species is also known as the Great Moor Blue and is one of the myrmecophilic species.
features
The upper sides of the wings are colored silvery light blue and have a series of delicate black dots. The dirty brown outer edges of the wing are provided with a white border drawing. The undersides of the wings are much lighter than those of Phengaris nausithous and are characterized by two rows of black dots. The inner row of dots is outlined in black and white, while the outer row is small and indistinct. There is a small blue basal pollination on the underside of the hind wing.

Geographical distribution and habitat
The species is very rare and only occurs locally in France ( Gers , Gironde , Dordogne , Charente , Isère , Savoie , Haut-Rhin ), northern Switzerland , northern Italy ( Piedmont , Trieste ), southern Germany, western Germany (Rhineland-Palatinate, Hesse and North Rhine-Westphalia), Central Germany (southern Leipzig area ), Austria , Hungary , Slovakia , southern Poland , Spain ( Valle de Arán ).
The Helle Wiesenknopf-Ant-Bläuling lives in flowery wet meadows and humid spring meadows in valleys and on mountain slopes as well as on streams and ditches. The occurrence of the species is linked to the presence of the great meadow button ( Sanguisorba officinalis ). The presence of fringing sites that are either not cultivated at all or are only cultivated irregularly plays an important role in the size of the population of the bluefin and its host ant.
Way of life
Development takes one to two years. The moths fly from mid-June to mid-August. They have a narrow spectrum of nectar plants. The most important nectar plant of the moths is the great meadow button . Visits to the flowers of purple loosestrife ( Lythrum spec. ), Medicinal ziest ( Stachys officinalis ), small brown elk ( Prunella vulgaris ) and bird vetch ( Vicia cracca ) were also observed . The female lays the eggs one by one on the not yet blooming heads of the Great Wiesenknopf. The young purple-red colored caterpillars first eat in the flowers of their forage plants and are carried into the ant nests of the dry grass knot ant ( Myrmica scabrinodis ) in autumn, after the third and last moult . They live there predatory on ants' brood. About 98% of the biomass of the pupa (and the later butterfly) comes from the resources of the ants. It has been estimated that about 350 female workers are indirectly needed to feed a Phengaris larva in the predatory Phengaris species ( P. teleius , P. arion and P. nausitous ) . This number is needed to provide the food for the brood of ants that the Phengaris larvae will eat. The myrmecophilic behavior of the Phengaris species is known as social parasitism . Pupation takes place in late spring of the following year or, in the case of caterpillars that remained small in the first year, in spring of the following year.
Parasites
Two of the three central European Phengaris species, which are predators of ants nesting, was known to be of parasitic wasps are parasitized (Ichneumonidae). In Phengaris nausithous it is the kind Neotype pusillus Gregor, 1940 and in Phengaris arion a specifically undetermined kind of neotype . It was only recently that it was also possible to prove that the light blue-colored ant is parasitized by a neotype species, presumably by neotype melanocephalus (Gmelin, 1790).
Hazard and protection
Due to the very local occurrence, limited by the occurrence of the host plant, the light blue-fly ant blue is at great risk.
- IUCN : endangered (vulnerable)

Like the dark blue blue ant, the light blue-colored meadow button is listed in Annex II and IV of the Habitats Directive and is therefore strictly protected at European level. According to Article 3, Paragraph 1 of this guideline, the member states must designate protected areas for the Natura 2000 network for habitats of this type and ensure the continued existence or, if necessary, the restoration of a favorable conservation status.
As in the Rhein-Sieg district, special protection projects are sometimes carried out. In the Rhein-Sieg district, a conservation project of running BUND for scarce large blue and dusky large blue simultaneously own Maculinea Foundation was established.
