Dysphaea ethela, [3] [1] the black torrent dart, [4] [5] is a species of damselfly in the family Euphaeidae. The insect is named after Frederic Charles Fraser's wife, Ethel Grace Fraser ( née Varrall) (1881-1960), a constant companion of his collecting trips in India. [2] [6]
It is found in Karnataka and Kerala and Tamil Nadu in Western Ghats. [1] This species is also known from the Eastern Ghats and central India. [7] [4] [8]
It is a medium sized damselfly with black head and brown-capped pale grey eyes. Its thorax is black, marked with narrow antehumeral and humeral greenish-yellow stripes. There are another yellow stripes on the base of lateral sides. These marks will get obscured by pruinescence in old males. Wings are transparent; but evenly enfumed with brown. Abdomen is black, marked with yellow apical annules up to segment 8. There are yellow lateral stripes up to segment 6. Anal appendages are black. [9]
Female is short and robust; the yellow marks are more broad and vivid. The yellow lateral stripes continued to segment 7. Segment 8 has a narrow and 9 has a broad yellow apical annule, covering dorsal half. [9]
It breeds in streams and rivers. Commonly seen perched on reeds or bushes on the river's bank or settled on rocks far inside the stream. [9] [2] [7] [4] [5]
