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]
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]
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).
Muscle memory helps you get back into shape faster after a break, makes complex movements feel more intuitive, and allows you to transition between similar activities easier (think: from tennis to ...
A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

Add a water feature like a small pond that's deep enough it won't freeze solid in frigid temperatures. It doesn't need to be big, but make sure it gets at least some sun. It doesn't need to be big ...
Historically its range did not extend into Scotland, but there are now some limited populations there. It is not found in Ireland or North Africa. [3] [2] [4] L. depressa is seen near still-water lakes and ponds, feeding on many types of small insects. They occur in both bare and sunny locations, where it is often the first dragonfly to ...
