Libellula lydia is in North America widespread dragonfly of the family of libellulidae .
features
Construction of the Imago
The male's thorax is approximately 2 inches long and white. In contrast, there are brownish-black markings on the otherwise transparent wings, similar to those of the Erythrodiplax umbrata . Females have a brown body with a few white spots and are therefore less conspicuous.
Construction of the larvae
The larvae are dark green or brown, but are mostly found covered with algae .
nutrition
The Libellula lydia feeds like most dragonflies of mosquitoes and other small flying insects which over ponds, marshland fly and slow-flowing streams.
The larvae prefer to feed on aquatic invertebrates such as larvae of mayflies and amphipods . But tadpoles and minnow are also on their menu.
Flight times
The flight times vary a bit with the area of distribution. For example, are Imagines in California active from April to September.
Systematics
Some places assign the Libellula lydia to the genus Plathemis instead of Libellula . This has been discussed since the end of the 19th century. Newer genetic methods support the thesis that splitting off L. lydia from the rest of the Libellula makes sense.
Scientific names
The first description of the species was provided by Drury in 1773 under its current name. In the same year de Geer described a male animal from North America that is now in Winthem's Collection as Libellula trimaculata . In 1793, Fabricius contributed another description under the name Libellula serra . In 1889 William Forsell Kirby described a specimen as Plathemis lydia , which he also used as a generotype of the genus Plathemis . It was Kirby who recognized the synonymy of the descriptions in 1890.
Protection status
Libellula lydia has protection status G5 worldwide , which means that it is classified as a large, widespread and non-endangered species. It received this status on December 30, 1985. In the USA and Canada it has the nationally equivalent protection status N5. Protection status has also been granted at the level of many states in the USA and Canada. These are shown in the graphic on the right.
