Summary

Eristalinae is a diverse subfamily of hoverflies with larvae that inhabit a range of environments, playing significant ecological roles in decomposition and water purification, while adults are known for their bee-like appearance and mimicry.

Physical Characteristics

Humeri pilose; mimicry of bees, especially honeybees (family Apidae).

Identification Tips

Look at the morphology of the eyes and wings to differentiate them from bees, specifically comparing them with family Syrphidae and order Hymenoptera.

Habitat

Moist, shallow aquatic environments, sap trails, under bark, in rot-holes in trees, in decaying organic material such as dung and compost.

Distribution

Approximately 500 species in 73 genera in the area.

Diet

Most larvae are saprophagous, feeding on decaying organic debris; some filter feed in aquatic media; others may feed on bulbs and are considered garden pests.

Life Cycle

Life cycle includes aquatic filter-feeding larvae as well as scavengers and leaf miners, depending on species.

Reproduction

Males patrol blossoms and wait near potential sites for females to lay eggs, employing dual mate-seeking strategies.

Ecosystem Role

Larvae purify water and contribute to the decomposition of organic materials.

Economic Impact

Some species are considered garden pests due to their feeding habits on bulbs.

Health Concerns

None stated.

Evolution

Part of the broader family Syrphidae, which consists of four subfamilies, with Eristalinae being one of them.

Misconceptions

Often misclassified as bees due to their mimicry.
