Family Coenagrionoidea -- Narrow winged damselflies
According to Wikipedia, The Coenagrionidae enjoy a world-wide distribution,
and are among the most common of damselfly families. There are about 40 Genera
in this family.
Family Lestidae - Spreadwing damselflies.
According to Wikipedia, Lestidae is a rather small family of cosmopolitan,
large-sized, slender damselflies.
They are of the order of the dragonflies (Odonata) and are commonly known
as "Spreadwings."
While most damselflies rest with their wings folded together,
most members of the family Lestidae hold them at an angle away from their bodies.
The pterostigma (a single dark spot in the meshwork of the leading edge
near the tip of each wing) is noticeably elongated.
The quadrilateral (a part of the wing venation, close to the body)
has an acute angle at the end. The body has a greenish metallic shine.
The superior anal appendages, commonly called claspers
(body parts of male insect for clasping the female during copulation)
of male spreadwings are long and strongly curved.
