( Fig. 20 c , Fig. 35 , Map 31 , Table 33)

Porcellio monticola was just recently discovered for the first time in Belgium in 2014 ( DE SMEDT et al., 2015). Most observations were done in ancient deciduous forests on calcareous soil, where the species was sometimes found in large numbers. The dominant tree species were always Oak ( Quercus petraea /robur) and Hornbeam ( Carpinus betulus ). There is one record from a calcareous grassland, but the location was close to ancient forest.

The limited number of records ( Fig. 35 ) does not allow for any conclusions on possible seasonal activity patterns.
