Saturniini is a tribe of giant silkmoths within the Saturniidae, encompassing some of the largest and most visually striking in the world. Members are characterized by their substantial body size, broad wings, and often elaborate wing patterns including prominent eyespots. The tribe includes well-known such as *Saturnia* and *Antheraea*. of many have reduced or non-functional mouthparts and do not feed, relying on fat reserves accumulated during the larval stage.

Identification
Saturniini are distinguished from other saturniid tribes primarily by their large size, with wingspans frequently exceeding 10 cm and some reaching 15 cm or more. They typically possess rounded forewings with well-developed, often concentric eyespot patterns on the hindwings. are strongly bipectinate (feathery) in males, particularly broad in some species. Larvae are generally large, cylindrical, and bear fleshy or scoli rather than urticating spines found in some related groups.

Distribution
The tribe has a broad distribution across the Northern Hemisphere, with major centers of diversity in the Palearctic region (Europe, Asia) and the Nearctic region (North America). Some extend into tropical and subtropical regions of Asia.
Life Cycle
Complete with , larva, pupa, and stages. Larvae feed on woody plants, often with specific associations at the or level. Adults of many species have atrophied mouthparts and do not feed; they survive on energy reserves stored during larval development. occurs in silken cocoons, which may be attached to vegetation or fallen leaves.
Behavior
are primarily and are attracted to light sources. Males use their broad, feathery to detect female from considerable distances. When disturbed, adults may display eyespots as a startle defense mechanism. Larvae are solitary feeders.
Ecological Role
Larvae function as herbivores on woody vegetation, with some occasionally reaching pest status in forestry or orchard contexts. serve as prey for bats, birds, and other . Their large size and abundance make them significant contributors to in temperate forest .
Human Relevance
Several have been used in for silk production, notably *Antheraea mylitta* (tussar silk) and related species in Asia. The large, attractive are frequently collected and are popular subjects in entomological displays and photography. Some species are minor forest pests when occur.
Similar Taxa
- AttaciniAnother tribe within Saturniidae containing giant silkmoths; distinguished by more elongate forewings, often more vivid coloration, and in some by the presence of elongated hindwing tails (as in *Luna *). Attacini are primarily New World in distribution, with limited overlap with Saturniini.
- BunaeiniAfrican saturniid tribe with large ; distinguished by distribution (primarily Afrotropical) and often by different wing venation and genitalic structures. Bunaeini includes many species with reduced eyespots compared to typical Saturniini.

Taxonomic Scope
The precise circumscription of Saturniini has varied historically. Modern molecular phylogenetic studies have clarified relationships within Saturniidae, though some generic placements remain under review. The tribe as currently recognized includes approximately 70-80 across multiple .
Conservation
loss and light pollution pose threats to some , particularly in fragmented temperate forest landscapes. Several European have experienced range contractions.
