About Acisoma panorpoides Rambur, 1842
Acisoma panorpoides is a small dragonfly. Males of this species have blue eyes. Their thorax is azure-blue, marbled with black to form a distinct beautiful pattern across the dorsum and sides. The abdomen is also azure-blue and marked with black. For abdominal segments 1 through 5, the sutures have fine black markings, while the ventral borders have broader black markings. A dorsal stripe runs along these segments, which widens at the jugal sutures and apical borders of the segments. A speckled stripe runs along the sub-dorsum of segments 1 to 4. Each of segments 3 to 5 has a large ventro-lateral black spot. Segments 6 and 7 are mostly black, with a large blue spot on each side. Segments 8 to 10 are completely black, and the anal appendages are bluish-white. Females are similar in general form to males, but have greenish-yellow eyes, thorax, and abdominal segments 1 to 5. The characteristic shape of the abdomen distinguishes this species from other members of the Libellulidae family. This species is widespread across Asia, ranging from the Indian subcontinent to Japan, the Philippines, and Indonesia. It occurs in subtropical or tropical swampy and marshy habitats. It has a very weak, short flight, and stays close to herbage and reeds in the heavily weeded ponds and lakes where it breeds.
