. Comstock Publishing Associates, Cornell University Press. The damming of rivers for … The wheel is formed when the male grasps the female behind the head and the female raises the tip of her abdomen forward to come in contact with the secondary genitalia of the male. Wings with a simpler venation, usually clear and only two antenodal crossveins. . During this time, the male dragonflies will hover roughly 0.5-1m away from their mate, and chase off any rival males that may be attempting to mate with the female. 1996. They have large compound eyes and short antennae and are equipped with chewing mouth parts. Species at higher altitudes or in dry environments usually have one generation per year while those in tropical habitats may undergo multiple generations per year depending on the availability of appropriate habitats. Females do not have secondary genitalia or grasping structures at the end of the abdomen but instead have a single genital opening and a small ovipositor at the end of the abdomen that will be used to oviposit her eggs (see above for types of oviposition). Females must find a suitable position to lay their eggs, as there are many factors that affect the success of the eggs. When the larva is ready to metamorphose into an adult, it climbs up a reed or other emergent plant. Dragonfly studies in the United States are in their infancy, as the study of birds was a century ago. . Whitetail females can be distinguished by their smaller size, shorter bodies, and white zigzag abdominal stripes; the abdominal stripes of L. puchella are straight and yellow. The large Dragonhunter is a type of Clubtail dragonfly, a group that generally has a wide tail tip (though not all do). Image Credit: Desira F., taken by the Duck River in middle TN, Updated: 8/23/2019; 5(4'). The two most common sources of mortality during the aquatic stage of life are predation and desiccation. Clutch sizes can be as large as 1500, with some females depositing several thousand eggs in a lifetime (Corbet 1999). After fertilization, the female deposits her eggs in emergent plants, floating vegetation or directly into the water. Florida Entomologist (1985): 39-51. The dragonfly and its young are carnivores, with adult dragonflies feasting mainly on flies, mosquitoes, bees and small invertebrate insects, while the larvae of the dragonfly feed on aquatic insects and insect eggs found on the water. In this hierarchy, dominant males have an advantage of mating with females over their subordinate counterparts. Head flat in dorsal view, with eyes separated by more than the width of a single eye. .

[2], Like all perchers, common whitetails often rest on objects near the water, and sometimes on the ground. In particular, the majority of the families that comprise Anisoptera are broadly distributed throughout the world. NOT separated by more than the width of an eye, Wing venation and wing shape in fore and hind wings NOT similar, usually clear and only two antenodal crossveins, Eyes touching broadly across top of the head, Eyes barely touching or touching only at a single point, lacking the cells that make up the "toe" region, longer than 1/4 the distance between the nodus and the end of R1, Last segments of abdomen usually enlarged.

Larger damselflies found in the forest or shaded areas along running streams.

This species may be completely green, including its eyes and wings, or it may be black with a yellow stripe running down its abdomen, and diagonal yellow stripes on the sides of its thorax. Corbet PS. Well developed loop forming a boot shape in hind wing.
