The flight muscles need to be kept at a suitable temperature for the dragonfly to be able to fly. Being cold-blooded, they can raise their temperature by basking in the sun. Early in the morning, they may choose to perch in a vertical position with the wings outstretched, while in the middle of the day, a horizontal stance may be chosen.
They are very conspicuous dragonflies; seen in swarms over paddy fields, playgrounds or open areas. They fly tirelessly with typical wandering flight for hours without making any perch. [8] Their flight speed is up to 5 m/s. [20] Especially in the autumn, the wandering glider flies in large swarms, using thermals to advantage.
Diplacodes trivialis [3] is a species of dragonfly in the family Libellulidae [4] known as the chalky percher [5] or ground skimmer. [ 6 ] [ 7 ] It is found in Seychelles , Oman , United Arab Emirates , China , Japan , India , Maldives and southwards to New Guinea and Australia .
They occur in both bare and sunny locations, where it is often the first dragonfly to colonise new habitats such as newly created ponds, and well vegetated ponds. L. depressa are often seen away from water as the adults are very mobile and undergo a period of maturation away from water after emergence. The adults are also migratory.
Incorporate some stones and native plants to give the dragonflies places to hide when they emerge from their nymph stage (they need a few days to become strong enough fliers that they can evade ...
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 ...
They are ambush predators, waiting on a prominent perch - such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger dragonflies away such as southern hawkers. This habit of repeatedly returning to a sunny spot allows you to easily ...
When newly emerged, the dragonflies at first hunt away from water. After about two weeks they return to the ponds and males set up territories, chasing away rivals. The males guard the floating algal mats that make suitable egg-laying sites. Satellite males remain nearby, awaiting an opportunity to intercept females or seize territories. [4]
