Habitat:
Pycnogaster inermis inhabits stony pastures, embankments and rocky slopes between ca. 1000 and more than 2200m asl.
Life cycle:
The animals develop quite early. I already recorded half-grown larvae in 1600-1800m asl in late March 2015 (Mulhacen S-side). Larvae kept themnselves under stones during daytime.
Remarks:
Pycnogaster inermis is endemic to Sierra Nevada in southern Spain.
