I'm not familiar with the Live Oak tree but take a close look at the leaves; especially around the area where the acorns are forming. See if there is any indication of honey dew and the presence of ants and/or aphids.
Interesting article and photo about oak galls also. >Honey bee on gall photo. >

"..gall tissue secretes sweet exudations which accumulate on the outer gall surface. These secretions are rich in sugars and serve as a food source for a wide variety of insects including small flies, large predatory wasps, butterflies and honeybees, with the latter usually the most abundant (figure 9). All of these gall visitors feed on the secretions until galls begin to dry in late fall."
