Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or above the abdomen. Dragonflies are ...
Aquatic insects live mostly in freshwater habitats, and there are very few marine insect species. [9] The only true examples of pelagic insects are the sea skaters , which belongs to the order Hemiptera, and there are a few types of insects that live in the intertidal zone , including larvae of caddisflies from the family Chathamiidae , [ 10 ...
Some taxa, like dragonflies, spend their adult stage outside the water. Other taxa, like water beetles, are aquatic for their entire lives. The evolution of different life history strategies of aquatic macroinvertebrates has allowed species to take advantage of differences in food supply and allow some to better tolerate extreme environmental ...
Freshly hatched nymphs live in subaquatic habitats until they become adult dragonflies. Their physical appearances differ greatly from their adult forms starting from the obvious lack of wings. Nymphs have six long legs, which help them navigate their underwater environment.
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 scarce chaser (Libellula fulva) is a species of dragonfly.The adult male has a bright blue abdomen with patches of black, while the adult female and juvenile male each have a bright orange abdomen.
Adults don't live long comparatively, perhaps a few weeks or months, and for this reason, Serafice says, dragonflies may also serve as a reminder to be present, enjoy life to the fullest and live ...
The widow skimmer (Libellula luctuosa) is one of the group of dragonflies known as king skimmers. The nymphs live in the water, molting and growing until they are ready to emerge from the water and then molting a final time to reveal their wings.
