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]
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
They forage very actively and eat fairly indiscriminately all sorts of aquatic invertebrates, such as aquatic insect larvae and small shrimps . Even tadpoles and small fish are used for food. The imago mostly eats small flying insects such as mosquitoes, swarming flying ants, and termites. [12]
The ancient critters, which developed some 300 million years ago and are among our planet's oldest insects, prey on bothersome mosquitos, with some dragonflies able to consume hundreds of the ...
The Odonatoptera are a superorder (sometimes treated as an order) of ancient winged insects, placed in the probably paraphyletic group Palaeoptera.The dragonflies and damselflies (which are placed in the subgroup Odonata) are the only living members of this group, which was far more diverse in the late Paleozoic and contained gigantic species, including the griffinflies (colloquially called ...
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 ...
An immature flame skimmer feeds mainly on aquatic insects. 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.
The adults look a bit like mosquitoes, though plumper, with antennae that are longer than their heads. They grow to 1/16- to 1/8-inch long and have light gray to clear wings.
