The fauna of peatlands
Peatlands home patrimoniale fauna linked to the present habitats. Some of these species are considered to be of community interest because they are in danger of extinction, vulnerables, rares or endemics (species from the Annex II of the Habitats-Faune-Flore directive).
Dragonfly
The Large white-faced darter (Leucorrhinia pectoralis)
Environment : mesotrophic stagnant water, slightly acidic to neutral and with the water surface dotted with vegetation (bogs areas with water holes and old extraction pits).
Biology : hatching 6 weeks after the pupae and larva stage from 2 to 3 years.
The Southern damselfly (Coenagrion mercuriale)
Environment : sunny, shallow, weakly running waters, with abundant aquatic vegetation and silty spots.
Biology : hatching from 3 to 6 weeks after the pupae and larva stage from 1 to 2 years.
The Lilypad Whiteface (Leucorrhinia caudalis)
Environment : eutrophic stagnant water, mesotrophic and oligotrophic in forest landscape.
Biology : hatching from 2 to 6 weeks after the pupae and larva stage of 1 year.
The Small Copper (Lycaena phlaeas)Butterfly
The Violet Copper (Lycaena helle)
Environment : wetlands (megaphorbia, low marshes, wet meadows) where can be find its host plant. The presence of bush is important for this glacial relic specie, wich like has a particular fondness for edge effects (night safe haven and frequent rest stops of the imagos).
Host plant : The common bistort (Polygonum bistorta).
Biology : their early emergence coincide usually with avec la floraison the blossominf of the aconite-leaf buttercup (Ranunculus aconitifolius). The imagos can be seen from early may and early july.
The Marsh fritillary (Euphydryas aurinia)
Environment : purple moor grass meadows, peaty ecosystems, limestone low marshes, wet moor-land. The imagos seem to be opportunists with their nectar sources, if they are diversified enought, but they need forest edges or groves of trees to reproduce.
Host plant : the devil's-bit (Succisa pratensis).
Biology : univoltine specie (one adult generation by year), caterpillar observation in late april or may fin avril and imagos observation between late may and late june.
The Dusky large blue (Maculinea nausithous)
Environment : wet meadows and marshes up until 1100 m.
Host plant : the great burnet (Sanguisorba officinalis).
Biology : flight in july and august. Caterpillar from august until june on the great burnet then in anthills (Myrmica rubra) where it hibernate.
The Scarce heath (Coenonympha hero)
Environment : clearing and wet edges up until 800 m.
Host plant : various monocotyledons, including the purple moor grass (Molinia caerulea) or the tufted hairgrass (Deschampsia cespitosa).
Biology : short flying period (mid-may until mid-june), eggs laid in isolation.
