Libellulidae
Plattbauch ( Libellula depressa )
The sails dragonflies or short Dragonflies ( Libellulidae ) are a family of dragonflies ( Anisoptera ). They belong thus to the dragonflies ( Odonata ). With 987 species, the sailing Dragonflies are the most species-rich family within the suborder dragonflies ( Anisoptera ) and represent the second most species-rich family of all families within the order Odonata ( dragonflies ) worldwide dar. In Germany there are 22 species, including some very common. As a relatively large dragonflies they are also usually very noticeable.
Features
The sails dragonflies reach body lengths of three to five centimeters and wingspans, which usually will be around eight inches. The animals usually have a yellow-brown drawing, sometimes with blue tires, and are never colored metallic. In some species, such as the Broad-bodied Chaser ( Libellula depressa ) the body is short and stocky. The wing triangle is aligned in the forewing of the body, the hind wings, however, perpendicular to the body. Except in the genus Diastatops his eyes touch on the top of the head. The ovipositor ( ovipositor ) of the females is reduced. The animals catch insects in flight, but are little perennial flyer; Exception, for example, Hiking Dragonfly - Pantala flavescens.
Reproduction and Development
The oviposition of the females occurs in the majority of species unaccompanied of the male. Exceptions to this are the darters of the genus Sympetrum. The eggs are released in the air by rocking movements of the abdomen directly into the water. Some darters lay their eggs on dry ground near the shore. In these, the development begins in the following spring when the spring flooding.
The larval development of the sailing dragonflies usually takes a year or two, where the larvae overwinter each once as young and late larva. The darters have a one-year development and overwintering occurs as an egg.
