The flight activity of Megachile nana Bingh 1802 foraging on alfalfa Medicago sativa L was related to some weather factors. The flight activity correlated positively with temperature, light intensity, solar radiation, nectar-sugar concentration and negatively with relative humidity. Bees were generally most active between 1200- 1400h. Path coefficient analysis revealed whether the relationship expressed by simple correlation was direct or indirect. Of the five factors studied, only relative humidity and solar radiation were found to influence flight activity directly.
