Ecological notes.

This epigean species can also be found in caves and MSS.

Seasonal patterns in Portuguese MSS habitats.

This species was found in four locations, Sicó, Alcobertas, Montejunto and Arrábida. In Sicó it was captured during spring and summer, with a higher abundance in spring (Fig. 7 B View Figure 7 ). In Alcobertas it was captured during all seasons, with abundance increasing towards summer and then decreasing till winter (Fig. 7 B View Figure 7 ). In Montejunto this species was also captured during all seasons, with abundance decreasing steadily towards fall and then staying the same in winter (Fig. 7 B View Figure 7 ). In Arrábida it was captured during spring, summer, and fall, with a steady decrease in abundance from spring to fall (Fig. 7 B View Figure 7 ).
