Why are honey bees on my live oak acorns?

Honey bees are likely visiting your live oak acorns to collect the sweet secretions, known as honeydew, produced by certain insects that may be feeding on the acorns. Additionally, they might be foraging for pollen if any flowers or other plants are nearby. Acorns themselves are not a primary food source for bees, but they can be attracted to the area due to the presence of other resources.
