Summary

Allantus is a genus of sawflies within the family Tenthredinidae, consisting of multiple species known for their larvae's leaf-feeding habits and the distinct appearance of adults.

Physical Characteristics

Members of the genus Allantus exhibit characteristics typical of sawflies, including a robust body, saw-like ovipositor in females, and distinctively shaped antennae and wings.

Identification Tips

Key to species available by Smith (1979), but primarily distinguished by variations in body coloration and patterns on the abdomen, especially for species like Allantus cinctus which is known as the Curled Rose Sawfly.

Habitat

Allantus species are commonly found in habitats where their host plants, typically various shrubs and trees, are present.

Distribution

Approximately 8 species are noted in the local area, with around 150 species globally.

Diet

Larvae primarily feed on the foliage of deciduous trees and shrubs; adults typically do not feed as they have a short lifespan.

Life Cycle

Allantus undergoes a complete metamorphosis, with a life cycle including egg, larval, pupal, and adult stages.

Reproduction

Females lay eggs in the host plant tissue, resulting in larvae that feed on the plant leaves.

Predators

Birds and various predatory insects may feed on Allantus as larvae or adults.

Ecosystem Role

As herbivores, larvae play a role in controlling plant growth, while adults may serve as pollinators.

Economic Impact

Certain species may have an impact on horticulture and agriculture due to their leaf-feeding habits.
