Biology
Bee flies are as their name suggests bee-like with large, fuzzy bodies and range from ¼ to ¾ inch in wingspan.
Despite spear-like mouthparts, they are pollen feeders and harmless.
Their larvae, however, are predators or parasitoids of a wide variety of mostly soil-dwelling insect immature stages including grasshoppers, beetles, wasps and bees.
Prey or Pest Targeted
- Mites, aphids, scale insects, thrips, caterpillars, beetle larvae, flies, wasps, grasshoppers, bees
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.
