Dragonflies

A dragonfly larvae is called a nymph. It kind of looks like a tiny alien creature. It lacks wings and has a hump on its back.

A butterfly uses a camoflage by its radiant colours for example a moth has a brown colour on its wings which helps it to hide in trees and become invisible to see for the predators to have its dinner and butterflies are also the same as the moth they use the same technique as the moth.

No. All insects have an external exoskeleton.

If a dragonfly follows you, it means they are going to try to eat you ! Hope I helped !!

Dragonflies do not live for only 24 hours. Dragonflies actually live for at least several months in a larval stage in ponds, and then emerge into adulthood as dragonflies which fly around. In this adult stage, dragonflies live for anywhere between a few days to several months and prey on other flying insects and look for a mate.

One reason might be that they are carnivorous predators and eat many smaller insects. The adults fly around and catch smaller insects in the air, while the larvae hunt smaller insects and other invertebrates under water. Also, many dragonflies are very large for insects. However they are completely harmless to humans and do not bite, sting or carry disease. In fact, they are good for humans because they eat harmful insects such as mosquitoes.

Bearded Dragons hunt in lots of different ways depending on the personality of the lizard and the food available. For example my Bearded Dragon will chase after the larger slower crickets but will stay still and wait for the smaller faster ones. Finally a Bearded Dragon's hunting patterns will also change based on the environment they are in e.g. a Bearded dragon that lives in a more open area with little hiding spaces might be more inclined to chase after prey compared to one who lives in a cluttered environment and will be more reserved and stealthy when hunting.

Dragon evolved from pterodactyls. When the meteor that ended the rest of dinosaurs hit the earth, the dragon ancestors then seculded themselves into deep cavernous lava caves. They lived within these lava caves for millions of years. They only started resurfacing during the middle ages in Europe. Since the cave systems in which the dragons live could not support very high populations, there were not very many at the time of surfacing. Knights then promptly eliminated the entire dragon population. It is still unknown if there are more dragons in the caves today. To answer your question, dragons were most likely first encountered by humans in the 600's in Europe. It is unknown when Asian dragons were first discovered.

The damselfly has 3 stages in it's life cycle. It consists of the egg, nymph and adult.

because if they have no food they will die and there food is our blood.

dragonflies normally fly between 7 to 9 ft. above or near water.

Nymph is the term for the immature form of an insect that undergoes incomplete metamorphosis. Metamorphosis helps insects to survive.

A dragonfly lives from about six months to several years.

One reason might be that they are carnivorous predators and eat many smaller insects. The adults fly around and catch smaller insects in the air, while the larvae hunt smaller insects and other invertebrates under water. Also, many dragonflies are very large for insects. However they are completely harmless to humans and do not bite, sting or carry disease. In fact, they are good for humans because they eat harmful insects such as mosquitoes.

All living organisms need to excrete waste, as this is one of the characteristics of life. When they are alive, dragonflies excrete waste.

The length of time it takes for a damselfly's eggs to hatch is dependent in part on the weather. The warmer it is, the more quickly they hatch. They typically need anywhere from 14 to 35 days to hatch.

Yes, many dragonflies will dine on snails if the opportunity presents itself. They also eat beetles, spiders, flies, gnats, and other pond insects.

Since,dragon fly nymph is in water once it has hatched from its egg it will breathe through gills.

Giant Dragonflies no longer survive but they were alive during the existence of the dinosaur. They could survive then because the percentage of oxygen in the air was higher than today, that's why the dragonflies are much smaller.

Dragonflies are messengers to remind us to tell the truth. They are also strongly associated with light. Illuminating those things that need to be brought into the light to chase out the shadows and the untruths.

Ophiogomphus susbehcha is the scientific name for the St. Croix Snaketail Dragonfly which is found mainly in a large, clean river habitat.

A safe mosquito traps involves an empty, uncapped 2-liter plastic soda bottle. Cut just below the point where the neck of the bottle straightens out onto the body of the bottle to create a cylinder and a funnel. Fit the funnel snugly into the cylinder. Fill about 1/3 of the cylinder with a mixture of 1 tablespoon of dry yeast, 1/3 cup of honey (or sugar) and warm water. Wrap a piece of black paper around this to make a nice warm comfy place for mosquitoes to hide. The trap works by creating carbon dioxide with the honey (or sugar) and yeast mixture. The escaping gas makes the mosquitoes fly into the trap, get stuck on the sweet-coated sides and wear themselves out trying to find an exit. Change the mixture about every two weeks or so.

A dragonfly's life span varies greatly. The shortest lifespan is around six-months, and there are those that live several years. Dragonfly's have inhabited the earth for around 300-million years.

They exchange gases with the environment by pumping them through a complex system of tubes called tracheae. (Modern Biology Book)
Dragonflies breathe through a complicated structure of tubes (called tracheae and tracheoles) and air sacs. Oxygen is pulled into the body through openings in their abdomens called spiracles. Once the oxygen has been pulled in, the outer most vents close and the air is forced into increasingly smaller pipes known as tubules, until it reaches the required cells.
