Ululodinae
Ululodinae is a subfamily or tribe (as Ululodini) of owlflies. Both they and the Ascalaphinae are sometimes known as split-eyed owlflies due to the characteristic ridge that bisects their compound eyes A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distin ....

Owlflies
Ascalaphidae is a family of insects in the order Neuroptera, commonly called owlflies; there are some 450 extant species. They are fast-flying crepuscular or diurnal predators of other flying insects, and have large bulging eyes and strongly knobbed antennae. The larvae are ambush predators; some of them make use of self-decoration camouflage. Description Owlflies are readily distinguished from the superficially similar dragonflies by their long, clubbed antennae; dragonflies have short, bristle-like antennae. The closely related antlions (family Myrmeleontidae) have short, weakly clubbed antennae, smaller eyes, and reticulate wing venation. All but one species of Ascalaphidae have long antennae, easily distinguishing them. The sole exception is the Brazilian '' Albardia furcata'', the only living member of the subfamily Albardiinae, which has short antennae, but these are strongly clubbed (compared to myrmeleontids), and its wing venation is reticulate, typical of ascal ...

Ascalaphinae
Ascalaphini is the type subfamily of the neuropteran owlfly family. Most species are found in the tropics. Their characteristic apomorphy , shared with the Ululodini, is the ridge which divides each of their large compound eyes; both groups are thus sometimes known as split-eyed owlflies. The group has been alternatly treated as a subfamily of Ascalaphidae, when the family is treated separate from Myrmelontidae, or as a tribe, when the ascalaphids are treated as a subfamily in an expanded Myrmelontidae. Like the other owlflies, they are insectivores. Imagines are cumbersome fliers and lack the strong mouthparts of dragonflies (which owlflies resemble at first glance, despite being not at all closely related insects) or other decidedly predatory insects, they are restricted to small and defenseless prey. The larvae on the other hand resemble antlions in appearance and habits and are voracious ambush predators, able to tackle prey like ants that will not be eaten without a ...

Compound Eyes
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color. The image perceived by this arthropod eye is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. Compared with single-aperture eyes, compound eyes have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the polarization of light. Because a compound eye is made up of a collection of ommatidia, each with its own lens, light will enter each ommatidium instead of using a single entrance point. The individual light receptors behind each lens are then turned on and off due to a series of changes in the light intensity during movement or when an object in moving, creating a flick ...

Myrmeleontidae
The antlions are a group of about 2,000 species of insect in the neuropteran family Myrmeleontidae. They are known for the predatory habits of their larvae, which mostly dig pits to trap passing ants or other prey. In North America, the larvae are sometimes referred to as doodlebugs because of the marks they leave in the sand. The adult insects are less well known due to their relatively short lifespans compared to the larvae. Adults, sometimes known as antlion lacewings, mostly fly at dusk or after dark and may be mistakenly identified as dragonflies or damselflies. Antlions have a worldwide distribution. The greatest diversity occurs in the tropics, but a few species are found in cold-temperate locations, one such being the European ''Euroleon nostras''. They most commonly occur in dry and sandy habitats where the larvae can easily excavate their pits, but some larvae hide under debris or ambush their prey among leaf litter. Antlions are poorly represented in the fossil re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
