About Heliocypha bisignata (Hagen, 1853)
Heliocypha bisignata is a small damselfly species. Males of this species have a black head and large eyes. The thorax is black, with pink markings on the dorsal surface and yellow stripes along the lateral sides. Their forewings are transparent, while the outermost fourth of the forewing is opaque and colored bright copper. The outermost third of the hindwing is opaque, marked with two series of vitreous spots that glow with a copper or violet reflection. The abdomen is black, marked with yellow mid-lateral stripes and dots on segments 2 through 6. Females have duller body coloration and fully transparent wings. The female pterostigma is black with a pale creamy center. Males are typically found perching on rocks, floating logs, and grasses along forest streams. They fly occasionally to display their glistening colored wing patches. Females lay their eggs in submerged logs within forest streams.
