Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. Damselflies have existed since the Late Jurassic, and are found on every continent except Antarctica.
The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, Australia, and Africa. The name refers to the club-like widening of the end of the abdomen. However, this club is usually less pronounced in females and is entirely absent in some species.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Trithemis kirbyi, also known as the Kirby's dropwing,orange-winged dropwing, or scarlet rock glider is a species of dragonfly in the family Libellulidae.
Leptophlebiidae is a family belonging to the Ephemeropterans that are commonly known as the prong-gilled mayflies or leptophlebiids. It is the only family in the superfamily Leptophlebioidea. There are around 131 genera and 640 described species. Leptophlebiids are easily recognized by the forked gills present on the larvae's abdomen, thus their common name.
Trithemis aurora, the crimson marsh glider, is a species of dragonfly in the family Libellulidae. It is a common and widely distributed species found throughout the year across the Indian subcontinent and Southeast Asia.
Euphaeidae, sometimes incorrectly named Epallagidae and commonly called gossamerwings, is a family of damselflies in the odonate superfamily Calopterygoidea. The family is small, consisting of around 78 species living species in nine genera occurring in the Palearctic, Australasia, and Asia. The family contains two subfamilies, Euphaeinae, encompassing all the living species and a single fossil genus, and the extinct Eodichromatinae, encompassing fossil genera from the Eocene to late Oligocene. Euphaeid species are large and mostly metallic-coloured, looking similar to species of damselflies in the family Calopterygidae.
Nanoraphidia is an extinct genus of snakefly in the family Mesoraphidiidae containing the species Nanoraphidia electroburmica and Nanoraphidia lithographica.
Hemiphlebiidae is a family of damselflies. It contains only one extant species, the ancient greenling, native to Southern Australia and Tasmania. The fossil record of the group extends back to the Late Jurassic, making them the oldest known crown group damselflies.
The Stenophlebiidae is an extinct family of medium-sized to large fossil odonates from the Upper Jurassic and Cretaceous period that belongs to the damsel-dragonfly grade ("anisozygopteres") within the stem group of Anisoptera. They are characterized by their long and slender wings, and the transverse shape of the discoidal triangles in their wing venation.
Amphiallagma parvum, little blue or azure dartlet, is a species of damselfly in the family Coenagrionidae. This species can be found in many South Asian countries including India, Sri Lanka, Myanmar, Thailand, Nepal, and probably in Bangladesh.
Pseudagrion rubriceps, saffron-faced blue dart, is a species of damselfly in the family Coenagrionidae. It is found in many tropical Asian countries.
Urothemis signata, the greater crimson glider, is a species of dragonfly in the family Libellulidae. It is widespread in many Asian countries. A number of subspecies are recognized for this species.
Perilestes is a genus of damselflies in the family Perilestidae. There are about eight described species in Perilestes.

Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
This paleoentomology list records new fossil insect taxa that were to be described during the year 2021, as well as notes other significant paleoentomology discoveries and events which occurred during that year.
