superfamily SUPERFAMILY is a database and search platform of structural and functional annotation for all proteins and genomes. It classifies amino acid sequences into known structural domains, especially into SCOP superfamilies. Domains are functional, str ...

dragonflies A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threaten ...

Libellulidae The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. E ...

Macromiidae The insect family Macromiidae contains the dragonfly species known as cruisers or skimmers. They tend to fly over bodies of water (and roads) straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely ...

Synthemistidae The Synthemistidae are the family of dragonflies commonly known as tigertails, or sometimes called southern emeralds. This family is sometimes treated as a subfamily of Corduliidae. This is an ancient dragonfly family, with some species occurr ...
