Agulla
Common Snakeflies
Agulla is a genus of modern snakeflies (Raphidiidae) characterized by an elongated prothorax that creates a distinct "neck" appearance. These predatory insects inhabit wooded areas and are associated with tree bark. The genus belongs to an order considered living fossils, with modern species closely resembling Jurassic-era relatives from 140 million years ago.
Agulla unicolor
Agulla unicolor is a species of snakefly (order Raphidioptera) in the family Raphidiidae, described by Carpenter in 1936. The species epithet "unicolor" refers to its uniform coloration. Snakeflies are predatory insects characterized by their elongated prothorax that gives them a distinctive 'necked' appearance. As a member of the genus Agulla, this species occurs in North America where it inhabits wooded environments. The larvae and adults are both predatory, feeding on small arthropods.
Alena
snakefly
Alena is a genus of snakeflies (order Raphidioptera) in the family Raphidiidae. These insects are characterized by their elongated prothorax that gives them a snake-like appearance. All species in this genus are predatory throughout their life cycle. The genus occurs in southwestern North America and parts of Mexico.
Alena minuta
Alena minuta is a species of snakefly in the family Raphidiidae, first described by Banks in 1903. The species is known from North America. Snakeflies (order Raphidioptera) are predatory insects characterized by an elongated prothorax that gives them a distinctive 'necked' appearance. As a member of the genus Alena, this species belongs to a group of small to medium-sized snakeflies.
Inocelliidae
Square-headed Snakeflies, inocelliid snakeflies
Inocelliidae is a small family of snakeflies (order Raphidioptera) containing eight extant genera plus fossil taxa. Members are commonly known as square-headed snakeflies due to their distinctive head shape. The family is distributed across the Northern Hemisphere, with extant species found in temperate forests of Eurasia and North America. Inocelliidae are holometabolous predators with larvae that inhabit bark and wood of coniferous and deciduous trees, where they prey on other insects. The family includes notable fossil representatives such as Fibla carpenteri from Baltic amber, the largest known snakefly species.
Negha meridionalis
Negha meridionalis is a species of square-headed snakefly described by U. Aspöck in 1988. It belongs to the family Inocelliidae, one of two families within the order Raphidioptera. The species is known from North America, though specific details about its biology and ecology remain poorly documented.
Raphidiidae
Raphidiid Snakeflies, Snakeflies
Raphidiidae is the largest family of snakeflies in the order Raphidioptera, comprising over 200 extant species. Members are characterized by an elongated prothorax that gives them a distinctive 'snake-like' appearance. The family is distributed across the Northern Hemisphere, with notable diversity in North America, Europe, and Asia. The genus Alena is considered the most morphologically distinct within the family due to unusual male genital sclerites. Snakeflies in this family are predators of small arthropods.
