Biology
Of the more than 200 species of Cuckoo wasps in North America, most occur in the west. Most species are metallic green, blue green or purple and superficially resemble green sweat bees.
They are parasitoids of other wasps and bees laying eggs on the prey of another wasp or on the gathered nectar/pollen of a bee.
Many Cuckoo wasps visit flowers and help in pollination while others tend to specialize in feeding on aphid honeydew.
Attracting and Keeping Natural Enemies
and Pollinators in Your Yard and Garden
- Native plants provide essential resources.
- Native flora also provides natural overwintering sites.
- Natural dispersion from nearby habitats ensures visitation.
- Some kinds of beneficial insects predatory mites are commercially available.
- Avoid regular use of synthetic, broad-spectrum pesticides.
- Infrequent use of certain narrow-spectrum pesticides is more compatible with some beneficials.
- Extensive lawns are also not conducive to attracting beneficial insects.
