Influence of a humid zone on entomocoenosis diversity.

The authors studied the insect diversity associated to humid and dry zones in the Caselli Nature Reserve (Pisa, Tuscany) in 2016 by using two Malaise traps. The average number of species and individual captures increased in the humid zone to about 118% for species and to 152% for individuals respectively. This richness increase was observed for some families of Coleoptera and Hymenoptera Aculeata and Apoidea. Surprisingly, a richness decrease of Lepidoptera (to 89% and 66% respectively for species and individuals) and Orthoptera (to 44% and 21% respectively for species and individuals) in the humid zone has been observed.
