A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large ...
The green darner is a large dragonfly; males grow to 76 mm (3.0 in) in length with a wingspan up to 80 mm (3.1 in). [9][10] Females oviposit in aquatic vegetation, eggs laid beneath the water surface. Nymphs (naiads) are aquatic carnivores, feeding on insects, tadpoles, and small fish. Adult darners catch insects on the wing, including ant ...
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies.The two groups are distinguished with dragonflies (suborder Epiprocta) 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 wings folded together along body at rest.
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). They resembled and are related to the present-day dragonflies and damselflies, and were predatory, with their diet mainly consisting of other insects.
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 ...
Kelli Hoover, professor of entomology at Penn State, noted lanternflies are also being gobbled up by certain types of wasps as well as wheel bugs. “In nature, nothing gets ignored,” she said ...
These dragonflies, like others of their infraorder, are carnivorous, and are capable of eating hundreds of insects every day, including mosquito and mayfly larvae. The adult dragonfly will eat nearly any flying insect, such as a moth or fly. Nymphs have a diet that includes other aquatic larvae, small fish, and tadpoles. [9]
Common worldwide or nearly worldwide genera are Aeshna and Anax. Anax includes some of the largest dragonflies, including the North American A. walsinghami, Hawaiian A. strenuus, European A. imperator and A. immaculifrons, and African A. tristis, but these are all exceeded by another member of the family, the Asian Tetracanthagyna plagiata, which by wingspan and weight is the world's largest ...
