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.
