Habitat:
Pycnogaster inermis inhabits stony pastures, embankments and rocky slopes between ca. 1000 and more than 2600m 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. In late September 2022 I recorded still two females in 2600m.
Remarks:
Pycnogaster inermis is endemic to the Sierra Nevada (and some adjacing mountain ranges) in southern Spain.
