The long distance effect of a small wormhole on correlation functions can be summarized as the insertion of a local "vertex"operator. We compute, to leading order in the size of the wormhole and in Planck's constant, the vertex operator for axionic wormholes. The effects of matter fields, primarily in the form of conformally coupled scalars, are also studied. The effective bilocal action does not seem to factorize, clouding the notion of a local vertex operator.
