Ascalaphinae
split-eyed owlflies, owlflies
Ascalaphinae is the type subfamily of the owlfly family Myrmeleontidae (order Neuroptera), distinguished by the diagnostic apomorphy of a ridge dividing each large compound eye—hence 'split-eyed owlflies.' This trait is shared with the subfamily Ululodinae. The subfamily is predominantly tropical in distribution and represents one of two main lineages of living Ascalaphidae, the other being Haplogleniinae with unsplit eyes. The first fossil record dates to the Miocene, suggesting Paleogene origin.
Ascaloptynx
owlflies
Ascaloptynx is a genus of owlflies established by Banks in 1915. The genus contains at least two described species: Ascaloptynx appendiculata (Fabricius, 1793) and Ascaloptynx oligocenica Nel, 1991. Owlflies in this genus share the characteristic features of the family Ascalaphidae, including large compound eyes and raptorial forelegs adapted for predation.
Myrmeleontidae
Antlions, Antlion lacewings, Doodlebugs, Owlflies
Myrmeleontidae is a family of neuropteran insects comprising approximately 2,000 species, commonly known as antlions or antlion lacewings. The family is best known for the distinctive predatory behavior of its larvae, which in many species construct conical pit traps in sandy soil to capture prey. Adults are aerial insects with delicate, often patterned wings, and are frequently mistaken for dragonflies or damselflies. The family includes two traditional subfamilies: Myrmeleontinae (antlions) and Ascalaphinae (owlflies), though the latter is sometimes treated as a separate family. Antlions exhibit remarkable diversity in larval hunting strategies, with pit-digging behavior restricted to certain genera while others employ ambush or roaming predation.
Myrmeleontiformia
Antlions, Owlflies, and Allies
Myrmeleontiformia is a monophyletic suborder of lacewings (Neuroptera) containing approximately 2,160 described species across two superfamilies: Myrmeleontoidea (antlions, owlflies, spoonwings, and split-footed lacewings) and Psychopsoidea (silky lacewings and extinct families). The group is predominantly diverse in arid tropical and subtropical regions. Members exhibit diverse larval predation strategies, including the famous pit-building behavior of some antlions.
Oliarces clara
Cheeseweed Owlfly
Oliarces clara is a species of owlfly in the family Ithonidae, commonly known as the Cheeseweed Owlfly. It is a neuropteran insect native to North America. Owlflies in this family are generally nocturnal or crepuscular predators, though specific behavioral details for this species remain poorly documented. The species was described by Nathan Banks in 1908.
Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.

Ululodes macleayanus is a species of owlfly in the tribe Ululodini, family Ascalaphidae. It is widely distributed across the Caribbean, Central America, North America, and South America. The species is characterized by divided eyes and clubbed antennae. Adults are known for a distinctive cryptic resting posture where the abdomen projects from the perch to resemble a twig.
Ululodes quadripunctatus
Four-spotted Owlfly
Ululodes quadripunctatus, commonly known as the four-spotted owlfly, is a species of owlfly in the family Ascalaphidae and tribe Ululodini. The species is distributed across Central America and North America. Owlflies are neuropteran insects that share characteristics with both dragonflies and butterflies, possessing large eyes, many-veined wings, and long clubbed antennae.
