History and Objectives: Considering the high frequency of the scorpion Mesobuthus eupeus in Iran and the critical significance of its biting, this study was carried out to determine its distribution pattern using rock-rolling and black light trapping methods in Kashan from 2000 to 2001.

Materials and Methods: The descriptive strategy of this study was carried out on 29 places in Kashan and with 44 samples using rock-rolling and black light trapping methods in Kashan from 2000 to 2001.

Results: Out of 29 locations, 44 sampling were done and a total of 239 scorpions were trapped. In this respect, 227 (95%) out of them were trapped using rock-rolling method and 18 samples (5%) were collected using black light method. The average rate of sampling was 5.43. The average was 7.56 for rock-rolling method and 1.28 for black light method.

Conclusion and Recommendations: It was found out that in mountainous locations, more scorpion is trapped using rock-rolling method and the scorpion Mesobuthus eupeus is mainly lithophilic and psammophilic.
