FOOD/FEEDING

What does it eat? small fish, other invertebrates, and tadpoles

What are some special adaptations? The dragonfly nymph has very large eyes that it uses to see its prey, and its predators. It also has a 'mask' that it uses to shoot out and catch its prey.

HABITAT

Where does it live? Is it a climber, a swimmer, a digger, ect? Usually, a dragonfly nymph lives in marshes or still water. They can also live in water with high salinity. (High salt levels)But they cannot live in polluted water; they usually require very clean water. They require shelter, sunlight, unpolluted water, emergent plants and hunting areas.

What conditions does it prefer? The nymph can live in select areas; it prefers still, fresh water.

What are some special adaptations? They move around by squirting jets of water and pumping water in and out of the bottom of its abdomen. It also has gills so it stays under water for its nymph life.

PREDATORS

Who eats it? Large insect larva, leeches, and fish.

How does it keep from being eaten? It usually crawls along the bottom of the habitat and moves quickly.

What are some special adaptations? It has developed to be camouflaged over thousands of years.

STATUS/THREATS

Is your BMI common? Rare? Endangered? No, dragonfly nymphs can be found many places around the world.

What factors influence its survival? Its speed, its camouflage, and its hunting skills.

FIELD ID

How to find a dragonfly nymph.

Look for these characteristics.
Nymphs have "lips" hinged in two places with grasping
pincers on the end for catching prey. Brown and green bodies tend to provide
camouflage and allow the nymph to blend in with the habitat of plants and
pond bottoms. Gills inside the abdomen get the oxygen from the surrounding water. Water drawn into the
abdomen a nd through the gills is expelledto push the nymph through the water.
Dragonfly nymphs require 4 to 8 ppm of dissolved oxygen to survive.
.
 They have three segmented legs. You can distinguish a dragonfly nymph from a damselfly from the round to oval shape of the body that ends in wedge shaped tails. It is also helpful to use a diagram to identify the nymph.

METAMORPHIS
The dragonfly goes through an incomplete metamorphis.  It starts as an egg, then goes to a nymph, then finally its adult stage. This entire process can take at least a year. This metamorphis can vary depending on the type of dragonfly. Here is a video that shows this life cycle.
 REPRODUCTION
 Dragonflies mate in the air, then the female lays the eggs in the water.
