A dragonfly may consume as much as a fifth of its body weight in prey per day. [77] Dragonflies are also some of the insect world's most efficient hunters, catching up to 95% of the prey they pursue. [78] The nymphs are voracious predators, eating most living things that are smaller than they are.
Males also have secondary genitalia (including the anterior lamina, hamuli and posterior lamina) on S2 and S3. Female damselflies and some dragonflies have a strong ovipositor on the underside of S8 and S9, but in many dragonflies the egg-laying apparatus is merely a spout, a basket, or a pair of flaps. Some species have foliations (leaf-like ...
The development of general thrust is relatively small compared with lift forces. Lift forces may be more than three times the insect's weight, while thrust at even the highest speeds may be as low as 20% of the weight. This force is developed primarily through the less powerful upstroke of the flapping motion. [9] [16]
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 ...
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).
Dragonflies also can specifically symbolize self-awareness, self-love and embracing your own personal power—and the abundance that reaching your potential can bring.
