Summary
Chalcoela is a genus of moths in the Crambidae family known for their parasitic relationship with paper wasps, particularly species of Polistes. Their lifecycle interacts closely with wasp habitats.
Physical Characteristics
Moths of the genus Chalcoela have distinctive markings on their hindwings which inspired their name, deriving from Greek terms for 'copper' and 'nail'.
Identification Tips
Look for unique webbing in wasp nests, which is indicative of Chalcoela larvae activity.
Habitat
Typically found in areas where paper wasp nests are present, such as yards and open fields.
Distribution
Found across North America, specifically in California, Arizona, Texas, South Carolina, Michigan, and Ontario.
Diet
The larvae of Chalcoela are parasitoids of paper wasps, specifically feeding on the larvae and pupae of Polistes species.
Life Cycle
Chalcoela moths have several generations per year. Their caterpillars spin webs in the cells of the wasp nest, and they can overwinter in these nests.
Reproduction
Reproduction occurs within the confines of wasp nests where the female lays eggs on or near wasp larvae.
Predators
Predators may include other insects, birds, and possibly some mammals that can access the nests.
Ecosystem Role
Chalcoela moths play a role in regulating wasp populations as they are parasitoids of their larvae.
Collecting Methods
- Traps placed near wasp nests
- Visual inspection of wasp nests for larvae
Preservation Methods
- Pressing specimens
- Freezing specimens for a few days to kill parasites
