Petaluridae thumbnail
Petaluridae
The petaltails, also called graybacks, of the family Petaluridae are among the most ancient of the extant true dragonflies (infraorder Anisoptera), having fossil members from as early as the Jurassic, over 150 million years ago. A 2024 molecular phylogeny found that the petaltails comprise two clades, a Gondwanan clade and a Laurasian clade. Their divergence time was estimated at 160 million years ago.
Macromiidae thumbnail
Macromiidae
Macromiidae is a family of dragonflies. The family contains species known as cruisers or skimmers. They are known to fly over bodies of water and roads. They are similar to Aeshnidae in size, but with green eyes that barely meet at the top of their head.
Epiophlebia thumbnail
Epiophlebia
Epiophlebia is a genus of damsel-dragonfly native to the Indian subcontinent, East Asia, and Southeast Asia. It is the only living genus of Odonata to be neither a dragonfly nor a damselfly. It is the sole member of the family Epiophlebiidae, which is itself the sole living representative of the infraorder Epiophlebioptera. It was historically regarded and is still often regarded by neontologists as being of the suborder "Anisozygoptera", but the traditional classification of this group including fossil species has been shown to be an unnatural paraphyletic assemblage.
