The reproductive behaviour of Orthetrum sabina (Drury, 1770) was studied at Asan Conservation Reserve-RAMSAR site, Uttarakhand, India during 2022-2025. The Courtship is well marked and male demonstrate a circular territory with a radius of about 1-4 meters. Before Wheel tandem lasted for a 6-20 seconds in the air. The copulatory wheel formed in the air during chase by male to the female in the territory and is performed on perching the vegetation, which lasts for about 8-10 minutes. In the air copulatory wheel break, the After Wheel tandum lasted for about 10-15 seconds, the male release the grip on female in the territory and female freely laid eggs by dripping the tip of the abdomen 25-32 times on the surface of the water among the aquatic vegetation exophytically. The male hovers continuously in the air and guarded the female during oviposition from inter or intra specific males. After laying the first batch of the eggs, the female along with male took rest of 10-20 seconds on the twig of vegetation, before going for the next batch. The oviposition completed within 2-4 minutes. The complete reproductive behavior duration varies from 12-20 minutes.
