Caddis
The caddisflies, or order (biology), order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while Annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and Molecular phylogenetics, molecular analysis suggests it may not be Monophyly, monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous insect wing, wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larva ...

Hydroptiloidea
The Hydroptilidae are a large family of caddisflies (Trichoptera) with a worldwide distribution. They are commonly known as microcaddisflies or purse-case caddisflies, in reference to two characteristic traits of this family: Hydroptilidae are much smaller than other caddisflies, rarely exceeding in length. Their larvae do not build a protective case until the final instar of their growth. At that time however, they build a typically Purse-shaped case, either portable or stuck to the substrate, in which the larva finishes growth and pupates. Systematics and taxonomy Their systematic placement among the caddisflies is still disputed. They are traditionally placed in the suborder Spicipalpia, which do not seem to be a natural monophyletic group, but rather an evolutionary grade of moderately advanced caddisflies. Some authors downrank the Spicipalpia to a superfamily of the more basal Annulipalpia and call them Rhyacophiloidea (which otherwise refers to a subfamily of sub ...

Fly Fishing
Fly fishing is an angling method that uses a light-weight lure—called an artificial fly—to catch fish. The fly is cast using a fly rod, reel, and specialized weighted line. The light weight requires casting techniques significantly different from other forms of casting. The flies may resemble natural invertebrates, bait-fish, or other food organisms. Fly fishing can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species, notably bass. In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout and salmon versus coarse fishing for other species. Techniques for fly fishing differ with habitat (lakes and ponds, small streams, large rivers, bays and estuaries, and open ocean.) Author Izaak Walton called fly fishing "The Contemplative Man's Recreation". Overview In fly fishing, fish are caught by using artificial flies that ar ...

Helicopsyche
''Helicopsyche'' is a genus of Trichoptera, the caddisflies. ''Helicopsyche'' contains more than 230 species and are represented on all major faunal regions with highest diversity in tropical and sub-tropical regions. The genus was first described by Siebold, 1856. The abundance and wide distribution of the genus makes it important to fly fishing anglers, who know it as the "Speckled Peter". Diagnosis Larva: The case is dextrally coiled, with coils usually completely fused. Head is oval in dorsal view and smooth except for long setae and lateral carina. In lateral view the head has a trianguloid shape with the dorsal margin straight or slightly concave. Pronotum is strongly sclerotized while meso-and metantoum are weakly sclerotized. Anal claw with a single row of comb shaped hooks. Abdominal gills either are present or absent. Adult: maxillary palps 2-, 3-, or 4-jointed. Antennae as long as fore wing or two times longer than fore wing length. Cephalic warts variable. One pai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Duprat
Hubert Duprat is a French artist known for his unusual work, an artistic intersection between caddisfly larvae and gold, opal, turquoise and other precious stones. Caddisfly larvae live in fresh water and naturally construct elaborate protective tubes for themselves from materials found in their environment. Under natural conditions they use the objects found in their stream bed homes such as pieces of wood, fragments of fish bone or crustacean shell, grains of sand, plant debris and small stones. The tubes serve various purposes; the stones are used to increase traction in fast-moving streams, they serve as disguise for the soft-bodied insect and the spiky bits make the tube and thus, the fly larva, more difficult for predators to swallow. Duprat, born in 1957, began his work with caddisfly larvae in the early 1980s. He collects the larvae from their normal environments and he takes them to his studio. There he gently removes their own natural cases and puts the larvae in tank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the b ..., the caddisflies. The name refers to the unringed nature of maxillary palp's terminal segment in the adults. Integripalpian larvae construct portable cases out of debris during the first larval instar, which are enlarged through subsequent instars. These cases are often very specific in construction at both the family and genus level. External linksTree Of Life Integripalpia Page Insect suborders {{Trichoptera-stub ...

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insect Wing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Those i ...
