Physical Characteristics

Generally 2 to 4 mm long, metallic blue black, stoutly built, with broad high head and clear wings. The frons is densely setulose, and they have only a single pair of abdominal spiracles.

Habitat

Tropical countries; specific habitat details not provided.

Distribution

One species is intentionally introduced in California; overall, 34 species known across three genera, primarily in tropical regions.

Diet

Reproduction

Details on reproduction not provided.

Predators

Predators not specified; possible implications due to parasitoid lifestyle.

Conservation Status

Not indicated.

Ecosystem Role

Biological control agents due to their role as endoparasitoids of scale insects.
