The taxonomy and distribution of dragonflies

So, for example, all organisms in the kingdom Animalia share characteristics that make them different from organisms in another kingdom, Plantae. Dragonfly wings behave highly dynamically during flight, flexing and twisting during each beat. One record from Sedgwick Co. The Anisoptera - Three Families.

A good project would be to regularly collect all exuviae from a certain area. Photo by Roy Beckemeyer, Sedgwick Co. Cordulegaster obliqua, Arrowhead Spiketail Female. Some families appear to use special mechanisms, as for example the Libellulidae which take off rapidly, their wings beginning pointed far forward and twisted almost vertically.

This name tells us that we are humans. Libellula pulchella, Twelve-spotted Skimmer Male. One record in Cherokee Co. Macromia illinoiensis, Illinois River Cruiser Male. It remains stationary with its head out of the water, while its respiration system adapts to breathing air, then climbs up a reed or other emergent plant, and moults ecdysis.

It has a chitinous exoskeleton of hard plates held together with flexible membranes. Some dragonflies signal ownership with striking colours on the face, abdomen, legs, or wings. You could make a real contribution to our understanding of them by careful observation and record-keeping.

State Lake, KS, Aug. Photo by Roy Beckemyer, Scott Co. This could be true as well of the Kansas specimens, but there was insufficient material available to us at this time to make a definitive assessment given the slight differences between the species descriptions.

However, there has not been accumulation of extensive baseline data on spatial distribution of these insects from such places. The female in some families has a sharp-edged ovipositor with which she slits open a stem or leaf of a plant on or near the water, so she can push her eggs inside.

The eggs hatch and young naiads juveniles emerge, looking more like tiny lobsters than darners. Photo by Sid Dunkle, TX. By contrast, a "summer species" emerges over a period of weeks or months, later in the year.

The territory may be small or large, depending on its quality, the time of day, and the number of competitors, and may be held for a few minutes or several hours.

These facets provide complete vision in the frontal hemisphere of the dragonfly. In the current taxonomic system, biological organisms are fitted into groups according to their characteristics. Celithemis eponina, Haloween Pennant Female. Take dragonflies for example.

Maharashtra is divided into 35 administrative districts. One record, Crawford Co.

The average latitude of where records occurred increased by 78 km over these time periods. They tend to be slender and elongate, many having morphological adaptations for holding their position in fast flowing water. Photo by Sid Dunkle, TX.

Introduction to the Odonata

The male also has an eyespot on the head, giving it the appearance of a cyclops. Other dragonflies engage in aerial dogfights or high-speed chases.

Anisozygoptera, a previously recognized third suborder, has been merged with Anisoptera in recent revision of the taxonomy of Odonata (Bybee et al.Dumont et al. ). About 6, species of Odonata and subspecies belonging to genera have been documented world-wide.

Distribution In total 56 species (21 damselflies; 35 dragonflies; 27 genera; including 1 uncertain species and genus) of Odonata have been recorded in Extremadura.

Extremadura has one of the best mapped dragonfly faunas of Spain to date thanks to Los Odonatos de Extremadura (Sánchez et al. ). A new Epiophlebia (Odonata: Epiophlebioidea) from China with a review of epiophlebian taxonomy, life history, and biogeography.

Phylogeographic analysis elucidates the influence of the ice ages on the disjunct distribution of relict dragonflies in Asia.
