Summary
Diodontus is a genus of wasps known for their parasitoidal behavior towards aphids, with larvae feeding on the aphid species provided by the female wasp.
Physical Characteristics
Adults are wasps and exhibit typical wasp morphology; larvae are elongated and live within aphid colonies.
Identification Tips
Identify by the presence of specialized mouthparts adapted for feeding on aphids and their nesting behavior.
Habitat
Typically found in habitats where aphids are abundant, including gardens and agricultural fields.
Distribution
Diodontus species are distributed across Europe, Africa, and Northern America.
Diet
Larvae feed on aphids provided by the mother; adults may feed on the juices of aphids but do not consume them entirely.
Life Cycle
Involves egg-laying in or near aphid colonies; larvae develop inside the host's habitat.
Reproduction
Females provision nests with aphids for their larvae, ensuring a food source upon hatching.
Ecosystem Role
Acts as a biocontrol agent by preying on aphids, thus regulating aphid populations.
Collecting Methods
- Netting adults during warm months
- Searching for nests in the soil or near aphid colonies
Preservation Methods
- Pinning specimens for museum collections
- Storing in ethanol for molecular studies
