An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies , which make up the other odonatan infraorder ( Zygoptera ) and are similar in body plan , though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while ...
The green darner is a large dragonfly; males grow to 76 mm (3.0 in) in length with a wingspan up to 80 mm (3.1 in). [ 9 ] [ 10 ] Females oviposit in aquatic vegetation, eggs laid beneath the water surface.
It is a medium-sized dragonfly with a wingspan of 60-85mm. Adults are greyish to greenish yellow with black and pale markings and green eyes. Its abdomen is greenish-yellow, marked with black. [8] It is very similar to Orthetrum serapia in appearance, with both species appearing in northern Australia.
Adults don't live long comparatively, perhaps a few weeks or months, and for this reason, Serafice says, dragonflies may also serve as a reminder to be present, enjoy life to the fullest and live ...
The eggs hatch in 4 or 5 weeks and the larvae take one to two years to develop. The larvae live in the silt and detritus at the bottom of the pond, lying buried in mud with just the head and eyes showing. After emergence the adults move away from water and undergo a period of maturation which lasts 10 to 14 days.
Over the course of their adult lives the green of the male is gradually transformed into a duller shade of blue and finally a powdery bluish-grey. The wings are distinctively veined and have dark margins near the apices. [2] The length of this dragonfly is 36 to 48 mm (1.4 to 1.9 in). [3]
Epiophlebia superstes was originally considered to be part of the suborder Anisozygoptera along with the Himalayan Epiophlebia laidlawi, an intermediate clade between dragonflies and damselflies, mainly because their hind wings are very similar in size and shape to the forewings and held back over the body at rest, as in damselflies.

The adults of Onychogomphus forcipatus grow up to 6 centimetres (2.4 in) long, with a wingspan of 5.5–7.5 centimetres (2.2–3.0 in). The eyes of these medium-sized dragonflies are widely separated and grey-to-green. The two black lines on the side of the thorax are relatively narrow and touch the midline.
