Habitat:
Antaxius hispanicus inhabits mountain grasslands, rocky slopes, forest edges, embankments and dwarf shrubs in altitudes above 1200m asl up to 2400m.
Life cycle:
The adults appear between July and October or November. The mostly rest on the ground, but sometimes climb dwarf shrubs or herbs. They can occur in high densities.
Remarks:
Antaxius hispanicus occurs only in the Pyrenees of France, Spain and Andorra and further in small areas of the Spanish backland.
Antaxius chopardi which occurs in the same area (partly in somewhat lower altitude) can be separated best in some details of the female subgenital plate (carinated in chopardi). Additionally the wings are a bit shorter in A. copardi (males).
