About Ischnura senegalensis (Rambur, 1842)
This species is a small damselfly with black-capped bluish-green eyes. Its thorax is black on the dorsum and greenish-blue on the sides. Its abdomen is black on the dorsum up to segment 7. Segments 1 and 2 are greenish-blue on the sides, while segments 3 to 7 are khaki yellow on the sides. Segments 8 and 9 are azure blue; segment 9 is black on its dorsum. Segment 10 is black on the dorsum and khaki yellow on the sides. The green coloration on the thorax and abdomen of both males and females may turn blue as individuals age. Females of this species exhibit sexual mimicry. One group of females, called androchromes, mimics the male's coloration. The other group, called gynochromes, retains their own distinct female coloration. Androchrome females look exactly like males, differing only in sexual characteristics. In gynochrome females, the eyes are olive green with orange on the upper portion. The sides of the thorax are mud-colored, and pale as the individual matures. All abdominal segments are marked with black on the dorsum. The lateral sides are khaki yellow. Segments 1–2 and 8–10 have orange coloration on the lateral sides, which fades as the individual matures. This damselfly breeds in marshes, weedy ponds, and wetlands.
