Argia is agenus ofdamselflies of the familyCoenagrionidae and of the subfamilyArgiinae. It is a diversegenus which contains about 114 species and many more to be described. It is also the largest genus in Argiinae. They are found in the Western Hemisphere. They are commonly known asdancers. Although the genus name comes fromAncient Greek:ἀργία,romanizedargia,lit.'laziness',[1] dancers are quite active and alert damselflies. The bluerArgia species may be confused withEnallagma species.

Characteristics

[edit]

This genus of damselflies are known as dancers because of the distinctive jerky form of flight they use which contrasts with the straightforward direct flight ofbluets,forktails and other pond damselflies. They are usually to be seen in the open where they catch flying insects on the wing rather than flying about among vegetation picking off sedentaryprey items. They tend to land and perch flat on the ground, logs and rocks.[2] When perched, they usually hold their wing slightly raised above the abdomen.[3]

The males of most species are some combination of black and blue but they can easily be told from similarly coloured bluets by their mode of flight. Some species have red eyes and others a copper-coloured thorax. Many species have humeral stripes, either notched or forked at the end or narrowed in the centre. The wings have short petioles and are relatively broad close to the base.[2] Unlike most of the Coenagrionidae, dancers are often associated with flowing water.[3]
