Natural Habitat

Sunny, open habitats including gardens, woodland edges, meadows, and rocky areas; adults commonly rest on warm surfaces and visit flowers.

Diet & Feeding

Adults feed mainly on flower nectar and sometimes pollen using a long proboscis. Larvae are parasitoids or predators of solitary bee and wasp larvae and their provisions.

Behavior Patterns

Adults hover or dart rapidly while foraging, often mimicking bees with a fuzzy body and patterned wings. Females scatter eggs near solitary-bee nests; larvae enter nests and consume the host or its food stores.

Risks & Benefits

Harmless to people and unable to sting; the pictured species does not bite. Adults pollinate flowers, while larvae regulate solitary bee and wasp populations.
