Dragonflies

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.

Smaller insects, flying or nonflying. They're aerial predators, very fast and agile and with amazing eyesight (which you can also tell by its huge eyes and small antennae). They're entirely carnivorous, technically the birds of prey of the insect world.

the female dragonfly will sometimes submerge herself while laying her eggs. the male may just find a plase and die. the female dragonfly will sometimes submerge herself while laying her eggs. the male may just find a plase and die.

In Japan they are called tatsu, they've been called a drive of dragons or a flight of dragons (when flying), or a wing of dragons (when fighting), or a clan of dragons or finally, and my favorite, a rage of dragons!

Gills, flipperlike appendages to swim, and a 'mask', basically a facial pincer it uses to capture prey like small fish and bring to the mouth.

The dragonfly has adapted to the environment by evolving unique eyes that allow it to hunt very efficiently. They also have a smaller body size than their ancestors which allows the to fly faster and hunt less to support themselves.

There are several Families of dragonflies. If you are looking for the commonly used general classification name for them, the Order name for dragonflies and damselflies is Odonata. The Suborder for dragonflies is Anisoptera. Odonata Central (http://www.odonatacentral.org) has lots of photos and classification information if you are looking for the Family name for a particular type of dragonfly.

The dragonfly's weight is similar to that of a butterfly, around 0.0001 ounce (0.003 grams) for the smallest, to 0.1 ounce (3 grams) for the largest.

Well no, not really.

When it begins to rain a dragon fly takes immediate cover as its wings are very delicate and can crunch up. Once it has found a shelter it will make it wings vibrate so that the water droplets will slide off.

So overall the answer is basically no, it can't.

more than 117 species of dragonflies have been identified- over 184 if you include the damselflies, the members of the smaller suborder Zygoptera.
The fast flying insect the dragonfly has 5680 different species of dragonfly. And there are undoubtedly more that have not yet been discovered by scientists.

Insects typically have six or eight legs. Their legs are usually attached to the thorax, or center portion, of the insect's body.

Dragonflies generally capture insects on-the-fly. You may see dragonflies flying or waiting on a branch or cattail. When an unsuspecting insect comes flying along, they either launch toward the pray, or swoop in from above. This happens very fast. Dragonflies capture an insect by forming a sort of net with its legs. As they approach, they net the insect by coming in faster than the insect is flying, they fly very slightly higher than the insect, thus allowing the insect to slip into the net formed by its legs. They then eat the insect alive. Now, I do not know for sure if dragonflies actually pursue bees specifically, but if they do, this is the method used.
