Dragonflies having simple flaps shed the eggs in water, mostly in flight. Dragonflies having ovipositors use them to puncture soft tissues of plants and place the eggs singly in each puncture they make. [32] [34] [35] [36] Dragonfly nymphs vary in form with species, and are loosely classed into claspers, sprawlers, hiders, and burrowers. [17]
Its diet consists of mosquito larvae, aquatic fly larvae, mayfly larvae, freshwater shrimp, small fish, and tadpoles. The nymphs, which live in the mud at the bottom of warm streams or ponds, catch their prey by waiting patiently for it to pass by.
Compared to dragonfly larvae, the nymphs show little variation in form. They tend to be slender and elongate, many having morphological adaptations for holding their position in fast flowing water. They are more sensitive than dragonfly nymphs to oxygen levels and suspended fine particulate matter, and do not bury themselves in the mud. [25]
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
Naiads are found in rivers, streams, and lakes where there is water movement. They crawl in debris at the water's bottom and wait for prey. They mostly eat mosquito larvae, freshwater shrimp, fish and tadpoles (Young 1955). [2]
Larvae have a two-year developmental cycle. Adults feed predominantly on mosquitoes , gnats , and midges ; [ 1 ] the larvae feed primarily on other aquatic insect larvae and on tadpoles . There is a variant form, praenubila Newman, which has exaggerated wing spots.
Dragonfly nymph feeding on fish that it has caught with its labium and snatched back to the other mouthparts for eating. The labium is just visible from the side, between the front pairs of legs. The role of the labium in some insects, however, is adapted to special functions; perhaps the most dramatic example is in the jaws of the nymphs of ...
Naiads feed on a wide variety of aquatic insects, such as mosquito larvae, other aquatic fly larvae, mayfly larvae, and freshwater shrimp. They will also eat very small fish and tadpoles. Adult
