Arthropods form a cosmopolitan group that has been adapted to natural environments (deserts, forests, abysses, mountains. During the year 2018, using the methods of the filleting net, the barber pots and the direct collection, we inventoried the Arthropods in seven stations at the level of the Jebel SidiR'ghiss forest in the region of Oum El Bouaghi. The sampling yielded 1301 individuals belonging to 59 faunistic species. These stands are diverse with high Shannon-Weaver values. The numbers of stands are in equilibrium because the values of equitability are greater than 0.5. A total of five (5) animal classes (Malacostraca, Arachnida, Myriapoda, Insecta and Chilopoda); 13 Orders and 33 Families are inventoried in the seven stations. The Insect class is best represented with a rate of 88% Coleoptera order is the most abundant with an abundance rate of 25% followed by that of Hymenoptera with a rate of 24%. Formicidae is the most abundant family of the five harvested families of Hyminoptera.
