When you depend on Caddis, expect your outdoor adventures to last and last and last. These waders are the cat's meow!

I bought the Large, Short, Stout, and the sizing is perfect. I also bought a "used, like new" from amazon.

The only problem, was I had to buy new wading boots, one size larger than my normal 9 shoe. These have thicker neoprene stockings than my old waders.

I highly recommend these waders. I wore wool sucks underneath and had plenty of room while not feeling uncomfortable with flippers on, the top you can cinch up well so no water gets in while your posture gets lazy while floating.

I am 6' 1" pounds and the large fits perfectly. Will edit my review once I do some serious wading this winter. I purchased these waders in September.

I have fished about six times in them and they have been dry and warm every time. I'm 6'1" and weigh lbs. I ordered the Large size based on Caddis' fitting chart on their home page using my shoe size.

The fit is a little tighter than my old waders, but still comfortable. Like mayflies, stoneflies and dragonflies, but to a somewhat lesser extent, caddisflies are an indicator of good water quality; they die out of streams with polluted waters.

The newly hatched adult is particularly vulnerable as it struggles to the surface after emerging from the submerged pupa, and as it dries its wings.

The fish find these new adults easy pickings, and fishing flies resembling them can be successful for anglers at the right time of year.

The adult stage of a caddisfly may only survive for a few weeks; many species do not feed as adults and die soon after breeding, but some species are known to feed on nectar.

The larval stage lasts much longer, often for one or more years, and has a bigger impact on the environment. The fish acquire them by two means, either plucking them off vegetation or the stream-bed as the larvae move about, or during the daily behavioural drift; this drift happens during the night for many species of aquatic larvae, or around midday for some cased caddisfly species, and may result from population pressures or be a dispersal device.

The larvae may drift in great numbers either close to the bottom, in mid-water or just below the surface. The fish swallow them whole, case and all.

Caddisflies are best known for the portable cases created by their larvae. About thirty families of caddisfly, members of the suborder Integripalpia, adopt this stratagem.

These larvae eat detritus , largely decaying vegetable material, and the dead leaf fragments on which they feed tend to accumulate in hollows, in slow-moving sections of streams and behind stones and tree roots.

The cases provide protection to the larvae as they make their way between these resources. The case is a tubular structure made of silk , secreted from salivary glands near the mouth of the larva, and is started soon after the egg hatches.

Various reinforcements may be incorporated into its structure, the nature of the materials and design depending on the larva's genetic makeup; this means that caddisfly larvae can be recognised by their cases down to family, and even genus level.

The materials used include grains of sand, larger fragments of rock, bark, sticks, leaves, seeds and mollusc shells.

These are neatly arranged and stuck onto the outer surface of the silken tube. As the larva grows, more material is added at the front, and the larva can turn round in the tube and trim the rear end so that it does not drag along the substrate.

Caddisfly cases are open at both ends, the larvae drawing oxygenated water through the posterior end, over their gills, and pumping it out of the wider, anterior end.

The larvae move around inside the tubes and this helps maintain the water current; the lower the oxygen content of the water, the more active the larvae need to be.

This mechanism enable caddisfly larvae to live in waters too low in oxygen content to support stonefly and mayfly larvae. Larval case of Limnephilidae made of bitten-off plant pieces.

Case of Limnephilus flavicornis made of snail shells. In contrast to larvae that have portable cases, members of the Annulipalpia have a completely different feeding strategy.

They make fixed retreats in which they remain stationary, waiting for food to come to them. Members of the Psychomyiidae , Ecnomidae and Xiphocentronidae families construct simple tubes of sand and other particles held together by silk and anchored to the bottom, and feed on the accumulations of silt formed when suspended material is deposited.

The tube can be lengthened when the growing larva needs to feed in new areas. These larvae are carnivorous, resembling spiders in their feeding habits and rushing out of their retreat to attack any unwary small prey crawling across the surface.

Larvae of members of the family Glossosomatidae in the suborder Spicipalpia create dome-shaped enclosures of silk which enables them to graze on the periphyton, the biological film that grows on stones and other objects, while carrying their enclosure around like turtles.

The larvae have specialised mouthparts to scrape off the microflora that get trapped in the net as water flows through.

The larvae of other species of caddisfly make nets rather than cases. These are silken webs stretching between aquatic vegetation and over stones.

These net-making larvae usually live in running water, different species occupying different habitats with varying water speeds.

There is a constant drift of invertebrates washed downstream by the current, and these animals, and bits of debris, accumulate in the nets which serve both as food traps and as retreats.

Caddisfly larvae are aquatic, with six pairs of tracheal gills on the underside of the abdomen. The eggs are laid above water on emergent twigs or vegetation or on the water surface although females of some species enter water to choose sites.

Although most species lay eggs, a few in the genus Triplectides are ovoviviparous. Some species lay eggs on land and although most are associated with freshwater, a few like Symphitoneuria are found in coastal saline water.

Philanisus plebeius females lay their eggs into the coelomic cavity of intertidal starfish. Each of the usually ten abdominal segments bears a pair of legs with a single tarsal joint.

In case-bearing species, the first segment bears three papillae, one above and two at the sides, which anchor the larva centrally in the tube.

The posterior segment bears a pair of hooks for grappling. The pupal cocoon is spun from silk, but like the larval case, often has other materials attached.

When pupating, species that build portable cases attach them to some underwater object, seal the front and back apertures against predators while still allowing water to flow through, and pupate within it.

Once fully developed, most pupal caddisflies cut through their cases with a special pair of mandibles, swim up to the water surface, moult using the exuviae as a floating platform, and emerge as fully formed adults.

They can often fly immediately after breaking from their pupal cuticle. Emergence is mainly univoltine once per year with all the adults of a species emerging at the same time.

Development is within a year in warm places, but takes over a year in high latitudes and at high elevation in mountain lakes and streams.

The adult caddisfly is a medium-sized insect with membranous, hairy wings, which are held in a tent-wise fashion when the insect is at rest.

The antennae are fairly long and threadlike, the mouthparts are reduced in size and the legs have five tarsi lower leg joints.

Some species are strong fliers and can disperse to new localities, [25] but many fly only weakly. Once mated, the female caddisfly lays eggs in a gelatinous mass, attaching them above or below the water surface depending on species.

The fit is a little tighter than my old waders, but still comfortable. The X-large size would have just been too big. The waders come with a wading belt, a repair kit, and a mesh storage bag, though I don't use the bag I hang my waders up in the closet after they're dry.

There is also a nice front pocket where I can slide my reading glasses in and out of, as needed. These are good waders for the price.

The don't leak at all. The pockets are located in convenient places. The crotch is really long and comfortable, so if you are sitting in a fishcat, you won't get a wedgie.

Suspenders are nice and wide. The buckles haven't slipped and they are really easy to adjust while you are wearing them. If you aren't fishing and you sit in a chair, they don't run up your buttcrack.

The cladogram of external relationships, based on a DNA and protein analysis, shows the order as a clade , sister to the Lepidoptera, and more distantly related to the Diptera true flies and Mecoptera scorpionflies.

Lepidoptera butterflies and moths. Hymenoptera sawflies, wasps, ants, bees. The cladogram of relationships within the order is based on a molecular phylogeny using ribosomal RNA, a nuclear elongation factor gene, and mitochondrial cytochrome oxidase.

The Annulipalpia and Integripalpia are clades, but the relationships within the Spicipalpia are unclear. Caddisflies are found worldwide, with the greater diversity being in warmer regions.

They are associated with bodies of freshwater, the larvae being found in lakes, ponds, river, streams and other water bodies.

In the United Kingdom it is found in and around the county of Worcestershire in oakwoods. Caddisfly larvae can be found in all feeding guilds in freshwater habitats.

Most early stage larvae and some late stage ones are collector-gatherers, picking up fragments of organic matter from the benthos. Other species are collector-filterers, sieving organic particles from the water using silken nets, or hairs on their legs.

Some species are scrapers, feeding on the film of algae and other periphyton that grows on underwater objects in sunlight. Others are shredder-herbivores, chewing fragments off living plant material while others are shredder-detritivores, gnawing at rotting wood or chewing dead leaves that have been pre-processed by bacteria and fungi; most of the nutrients of the latter group come from consumption of the bacteria and fungi.

The predatory species either actively hunt their prey, typically other insects, tiny crustaceans and worms, or lie in wait for unwary invertebrates to come too close.

A few species feed opportunistically on dead animals or fish, and some Leptoceridae larvae feed on freshwater sponges. Like mayflies, stoneflies and dragonflies, but to a somewhat lesser extent, caddisflies are an indicator of good water quality; they die out of streams with polluted waters.

Individual species emerge en masse at different times, and are used one after the other, often for only a few days each year, as models for artificial fishing flies for fly fishing in trout streams.

Caddisflies are useful as bioindicators of good water quality , since they are sensitive to water pollution , and are large enough to be assessed conveniently in the field.

Together with stoneflies and mayflies, caddisflies feature importantly in bioassessment surveys of streams and other water bodies. While caddisflies in the wild construct their cases out of twigs, sand, aquatic plants, and rocks, the French artist Hubert Duprat makes art by providing wild caddisflies with precious stones and other materials.

He collected caddisfly larvae from the wild and put them in climate-controlled tanks. He removes the larvae from their original cases and adds precious and semi-precious items such as grains of gold into the tank.

The larvae then build new cases out of precious items, creating a unique form of artwork. The resulting works are sold across the world.
