Alderflies are megalopteran insects of the family Sialidae. Sialis lutaria a species of Alderfly in the genus Sialis. Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " The subphylum Hexapoda (from the Greek for six legs) constitutes the largest (in terms of number of species grouping of Arthropods and includes the Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Pterygota is a subclass of Insects that includes the winged insects Neoptera is a classification group that includes almost all the winged Insects specifically those that can flex their wings over their abdomens The Endopterygota, also known as Holometabola, are Insects of the subclass Pterygota which go through distinctive Larval Pupal The Neuropterida are a Clade of Holometabolous Insects Well-known members are the Lacewings Antlions and Dobsonflies Megaloptera is an order of Insects It contains the alderflies, Dobsonflies and fishflies, and there are about 300 known William Elford Leach FRS ( 2 February 1790 – 26 August 1836) was an English Zoologist and Marine biologist A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic Megaloptera is an order of Insects It contains the alderflies, Dobsonflies and fishflies, and there are about 300 known Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described In Biological classification, family ( Latin They are closely related to the dobsonflies and fishflies as well as to the prehistoric Euchauliodidae. The name dobsonfly refers to Insects of the Subfamily Corydalinae, part of the Megalopteran family Corydalidae. Fishflies are the members of the Subfamily Chauliodinae, belonging to the Megalopteran family Corydalidae. Stone Age Paleolithic See also Paleolithic, Recent African Origin, Early Homo sapiens, Early human migrations "Paleolithic" All living alderflies - about 66 species altogether[1] - are part of the subfamily Sialinae, which contains between one and about seven genera according to different scientists' views. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. In Biological classification, family ( Latin A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic But in most classifications, all or almost all of these are treated as subgenera of Sialis. In Biology, a subgenus is a Taxonomic rank directly below Genus. [2]

Sialinae have a body length of less than 25 mm (1 inch), long filamentous antennae and four large dark wings of which the anterior pair is slightly longer than the posterior. Sialis lutaria a species of Alderfly in the genus Sialis. Antennae (singular antenna) are paired Appendages connected to the front-most segments of Arthropods In Crustaceans they are Insect wings are outgrowths of the Insect Exoskeleton that enable insects to fly. In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species They lack ocelli and their fourth tarsal tarsal segment is dilated and deeply bilobed. An ocellus (plural ocelli) is a type of Photoreceptor organ in animals
The females lay a vast number of eggs upon grass stems near water. The larvae are aquatic, active, armed with strong sharp mandibles, and breathe by means of seven pairs of abdominal branchial filaments. A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example A gill is an anatomical structure found in many aquatic organisms When full sized they leave the water and spend a quiescent pupal stage on the land before metamorphosis into the sexually mature insect. A pupa ( Latin pupa for doll pl pupae or pupas) is the life stage of some Insects undergoing transformation Metamorphosis is a Biological process by which an Animal physically develops after Birth or hatching involving a conspicuous and relatively
Sialis lutaria is the most common alderfly in the United Kingdom[3] and across much of Europe. Sialis lutaria a species of Alderfly in the genus Sialis. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located
In addition to the living genus (or genera), there are several genera of fossil alderflies:[2]
- Dobbertinia (sometimes separated as subfamily Dobbertiniinae, but actually basal)
- Eosialis
- Proindosialis
The latter two are Sialinae. FOSSIL is a standard protocol for allowing serial communication for Telecommunications programs under the DOS Operating system. In Phylogenetics, a basal Clade is the earliest clade to branch in a larger clade it appears at the base of a cladogram
