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 ] These dragonflies are known to be voracious predators, consuming up to 10% of their body weight each day in food.
In the water, various species of ducks and herons eat dragonfly nymphs [82] and they are also preyed on by newts, frogs, fish, and water spiders. [84] Amur falcons , which migrate over the Indian Ocean at a period that coincides with the migration of the globe skimmer dragonfly, Pantala flavescens , may actually be feeding on them while on the ...
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 ...
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 ...
The chasers, darters, skimmers, and perchers and their relatives form the Libellulidae, the largest family of dragonflies. [2] It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species.
The emperor dragonfly [2] or blue emperor [1] (Anax imperator) is a large species of hawker dragonfly of the family Aeshnidae. It is the largest dragonfly in most of Europe, including the United Kingdom, [ 2 ] although exceeded in some areas by other species.
The naiads live in the debris of the bottoms of lakes and ponds. They do not actively pursue prey but wait for it to pass by, a strategy which affords them protection from other predators. The naiads emerge from the water to make the transition to adult dragonflies at night. Adults fly from early August through October.
According to recent research carried out by biologists at Rutgers University-Newark this species of dragonfly is the world's longest known distance insect traveller. Genetic evidence taken from dragonflies across the globe suggests that these small size insects are travelling vast distances to mate and are thus creating a worldwide gene pool ...
