The Larva of the caddis worm lives in water and carries out a full cycle of transformation. The insect is in the house of small stones and remnants of shells. A maggot used in fishing as bait and put on a hook, pre-fetched from their homes.

Description

Typical representative of the superorder Pocritical is the caddis worm. Adults resemble moths with pale color. They are small in size. The front part of the wings covered with hairs. The name of the insect-Trichoptera - comes from the Greek words “wing” and “hair”.

caddis larva

Best of all in the immediate vicinity of water develops caddis worm and its larvae. Habitat – neighborhood ponds. Serves as food for underwater creatures and a key part of the food chain. It is found in rivers, reservoirs, streams and lakes.

The Life cycle of the insect consists of eggs, larvae, pupae and butterflies. In the second stage it is a big part of life. The time interval between the pupation of eggs, and contacting the insect – 2 years. Interesting as food for fish in each stage. The doll harder to find as the plant on the hook, so the fishermen are dealing with the larvae. It concerns the caddisflies, creating around himself a house, as there are individuals living without it.

By the Way, fishing is not only used caddis worm-the larva of a dragonfly is also a bait, as a Mature insect, but there are some nuances. For example, an adult dragonfly peck fish living in the upper layers of waters, while the larvae successfully caught all the rest.

Reproduction

A Female caddis eggs are laid directly in plants. The preferred depth of the reservoir, because there the danger is less. There are species that reproduce on land. Caviar has a mucous consistency and the eggs are inside. It is a favorable environment for larval development. The growth of the shell is eroded or is removed from caddis. The shape of eggs and their clusters depends on the type. In most cases, it's oblong, or spherical lump of goo. Across the cords, resembling a donut or plate round shape. Eggs arranged spirally.

Development

The caddis Larva molts and grows along the way and it builds their house in the form of a tube, making it more roomy. After sheathing of the dwelling insect carry him along, drifting along the bottom. Out exposed chest, head and legs 2-3. In case of danger, the larva hides in a shell like a tortoise. Head closes the entrance. Surfacing for respiration require oxygen enters water through the abdominal covering and nourishes the blood. Larvae have tracheal gills, outgrowths on the abdomen bushy type. As the insect attaches the weighting agent to the house the stones or shells are small molluscs (empty or with inhabitants).

There Is a complete transformation of the insect. Pupae and larvae are at the bottom or in the water near the shore. As a result, the larva is transformed into an insect, whose head round shape, and the mouth is directed downwards. Compound eyes located on both sides. Top and front of no more than 3 dark of the eye, characterized by a rather complex structure. The direction of the optical lenses – in different directions. Have eyes on the forehead between antennae. The insect flies, using wings.

Habitat

The Movement of these insects in the grass occurs during the summer. The water is better heated by the sun in the shallow water region and there is more quantity of food available. The larva of the caddis will be on virtually every land drawn to a tuft of grass. Plants are full of this type of bait. The house of the caddis larvae looks like the case. As a binding material, the insect uses silk, which itself released. In this process applied the blades of grass, dead leaves, debris, sticks, sand, pieces of shells and small pebbles. In the home of the insect is held firmly, so it's hard to get it out without damaging. Caddis worm whose larva is an excellent bait eaten by the fish with cover. Familiar underwater creatures that is “dressed” option, so the cleaned specimens, which are much tastier, causing instant excitement. The larva of the caddis brings in this case a greater catch, but in use it efficiently maggots or worm. Thus caught perch, roach, pike, bream and other species.

Varieties

A Few of the caddis worm and its larvae. Description and way of life are somewhat different. Thus, some species live on the bottom, and the otherfloat to the water surface (houses made of light material – herbs that contain air). Their food – the pulp of the algae. This is caused by a large number of insects in plants.

Allocate a predatory species of caddis worm. Case they don't spin and very mobile. Using thin threads of insects clinging to rocks and shells on the bottom, opposed, equip a network of webs that look like a funnel. Power source – the mosquito larvae, small crustaceans and mayflies. This larva has a strong jaw – this helps to quickly kill prey. Such individuals are of little interest to fishermen, as hard as their search and storage. Preferable Siteki – larvae living in the house. They are picked by hand. Large number of them in the grass in the summer. Plants to consider this very carefully – once is not easy to notice the camouflage of the larva.

Mining

The Larva removes easily, especially if the fisherman has in this case experience. In case of danger, the caddis worm is completely immersed in the shell. Rear tip of the tube is compressed. On the other hand leans out the head. Take it gently and pull to remove the whole body. The insect has jaws and looks not the most pleasant way, but this should not be an obstacle. Knows his business, the fisherman acts confidently and without hesitation. You can be absolutely sure: finger caddis worm bite not. The bait get out of cover, pushing on the walls – the larva remains intact. A Naiad (a dragonfly larva) extracted in the same way.

Caddis as bait use at all times of the year. Mining in winter is different from summer. They are more complex, and methods of preparation. However, if you wish, everything is possible. This tradition came from Karelia, where traditionally welcomed by special prior arrangements for breeding fish bait. For example, before freeze-up was chosen the place on the river or the stream, and the bottoms fit bath brooms and stick them with stones. Before fishing got a broom, and when the fisherman began to shake, fell on the ice larvae. Next time on products new stick insects. The broom has become a shelter and sanctuary for caddis, especially when the subject is sprinkled with flour or fastened something to eat (bacon, bread).

Storing bait

Serious and experienced fishermen know how to keep the larvae of caddis. To do this, use a damp cloth, a box of plastic material, and apply strips of wet foam. Outside the house individuals quickly die. Long-term storage is possible when the bait laid out in a row and wrapped tightly to the insect did not leave home.

Cool caddis worm will live for another month. To make the larva moving before fishing, use a cloth bag placed in water. The polyethylene collected houses stack one layer at a small distance from each other, or during thawing may damage. On top put the second layer and placed in the freezer.

Acting carefully and scrupulously, the fishermen provide a bait on your next fishing trip: a pair of scissors to cut the right amount, and the rest put in a box. On the road to the pond is thawing, so it is subsequently easy mounting on the edge of the hook. Pre-larva freed from the house, if you are able to do it. Otherwise, the case breaking open or carry out a perforation with a pin the backside of the insect.

Usage

In the process of fishing a maggot nasazhivajut on a hook and use a bobber. In conditions of strong currents the bite is good: the float is deflected to the side or goes down quickly and lasts for a few moments, waiting. Fish eat caddis, and then made a sweep, and quickly wound the fishing line.how to keep the larvae of the caddis

The Goal, meanwhile, is trying to float away into the bushes. So she is not broke, keep the rod perpendicular to the shore, directing the prey to the center of the river. To the power of escaping fish increases over what challenges emerge. However, acting decisively, the fishermen get a solid catch.

Trying to use this bait, people are convinced of its effectiveness compared to worms and maggots, so apply constantly.
