I will discuss wormhole solutions in large classes of N=1 effective field theories characterized by the presence of several, and possibly many, fundamental axions. In setting the stage, I will propose a new EFT upper bound/estimate for the species scale. This upper bound will then be used to assess the consistency of the wormhole solutions. Some low-energy effects generated by the wormholes will also be discussed.
