How is a damselfly different from a nymph?
Damselfly nymphs are long and slender, and resemble a mayfly nymph more closely than a dragonfly nymph. Damselfly nymphs become adults after several molts, and the adult has a relatively shorter lifetime compared to nymph.
Are damselflies in the same family as dragonflies?
Damselflies are insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies.
What family are dragonflies in?
Dragonflies are in the suborder Anisoptera (different wings) because their larger hindwings are shaped differently than their forewings. The three dragonflies included here are all in the Skimmer family, Libellulidae.
Why is a damselfly called a damselfly?
Zygoptera (damselflies) means “equal winged,” while Anisoptera (dragonflies) means “unequal winged.” When they are not flying, damselflies usually hold their wings up over their backs (with the exception of spread-winged damsels), but dragonflies hold their wings open and to the sides.
Where are damselfly found?
Adult damselflies live near streams, lakes and ponds. The larvae live in streams, lakes and ponds among plants and rocks. Adult damselflies eat mainly flying insects. Larvae eat insects in the water, worms, and occasionally small fish.
How many wings does a damselfly have?
Damselflies are insect in the sub-order Zygoptera (meaning “pair-winged” or “equal-winged”). All four wings are of a similar size and shape. They are usually small, weak-flying insects that stay close to the water margins or water surface.
What family are damselflies?
The insect family Coenagrionidae is placed in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family.
What is another name for damselfly?
Odonata was until recently composed of three suborders: Anisoptera, commonly known as dragonflies; Zygoptera, commonly known as damselflies; and Anisozyoptera, as the name denotes, a morphological composite of the previous two suborders.
What do damselfly nymphs eat?
An adult damselfly will most likely stick to eating other insects, like mosquitoes and flies, but damselfly nymphs will eat anything that is an appropriate size in relation to their body. In both the wild and aquarium setting, they are known to eat small fish, shrimp, tadpoles, and small crustaceans.
Do dragonflies and damselflies mate?
Animal Sex: How Dragonflies Do It. Dragonfly and damselfly sex is a very conspicuous event, easily recognized by the heart-shaped “wheel” formation of mating pairs. Male dragonflies are very territorial and will ferociously defend their little mating area from other males.
How do damselfly nymphs eat?
Damselfly nymphs are predatory, feeding on aquatic insects. They capture prey by using a modified lower lip (called a labium) that shoots out rapidly and seizes the prey item. As adults they prey mainly on insects, small crustaceans, and fish, capturing their prey during flight using hind legs covered in hair.
What kind of insect is a damselfly nymph?
Damselfly nymphs are of the Odonata family, which includes Dragonflies and Damselflies. Damselfly Nymphs is the first stage of their life hood. It is here where they are aquatic predators of other aquatic insects, and also prey to Trout at the same time.
Which is the most common family of damselflies?
Coenagrionidae are also known as the pond damselflies, and is the most commonly encountered family worldwide, containing some of the smallest species, often with curved abdomens or tails and very thin wings. Damselfly Habitats – Where Do They Live?
Where do damselflies go when they turn into adults?
Damselflies catch prey on the bottom of the lake, but when they turn into adults, swim to the top. If you can simulate the Damselfly Nymph living on the bottom of the water, and then moving up to the top – you have a great chance of fooling a trout into biting. It simulates a Damselfly that is trying to escape to the top. Bam. Fish on.
How many generations does a damselfly have in one year?
Some can have even two generations in one year. Coenagrionidae is the most diverse and abundant family of damselflies. Nymphs live in wide range of freshwater ecosystems. They can be found in small ponds and streams, as well as in large lakes and rivers.
