This study was conducted at District Dir Lower, in north western Pakistan for the evaluation of diversity of Xylocopa spp. during March to September 2015. The study area was divided in 7 different localities namely Chakdara, Talash, Timergara, Jandol, Khal, Darmal and Lal Qilla. Higher Simpson’s index (1_D) values were calculated for Talash (0.7464) followed by Khal (0.7392), Chakdara and Jandol (same value 0.7366), Darmal (0.7268), Lal Qila (0.7244) and lowest value was calculated for Timergara (0.716). Divider and Scale method was used for the morphometric measurement of carpenter bees. Out of the total 321 specimens collected, four species namely, Xylocopa collaris, Xylocopa acutipennis, Xylocopa dissimilis and Xylocopa pubescens were identified. X. dissimilis was the abundant species recorded which represented 29.60 % of the total collection, while X. pubescens, X.collaris and X. acutipennis represented 27.60 %, 23.1 %and19.62 % of the total collection respectively.
