abstract
Considering the significance of behavioral study in the zoology, and knowing that scorpions make their own nest, the present study was conducted to monitor how the O. doriae (the Iranian domestic species) make their own nest. In this study, 24 live adult O. doriae species were collected from their natural habitats and kept separately in the plastic glass cage, sized 45×45×45 cm. The height of 20-25 cm embankment was prepared similar to the natural habitat, and it made wet by the rain wise spray of water. During 4 periods and each time 6 scorpions were kept in the cage. Then the data on the nest building was recorded and described. All of the scorpions under study started making nest at the down side of the soil embankment. The nest digging was done by holding the dorsal legs as a base and started digging with the help of the front three-pair legs. The excavation of the soil was done by the legs and the arc shaped tail. Concreting of nest was done by the tail.
