\label{fig:quiescent_fraction}  For allobserved  satellitesdwarf  galaxies with $\mstar\lessim10^9\msun$  within $300\kpc$ of the Milky Way (MW) or Andromeda (M31), the fraction that are quiescent ($\mgas/\mstar<0.1$) versus stellar mass, $\mstar$. Blue circles show all satellites, violet squares (green triangles) show those of just the MW (M31).  Of these 56 satellites, only 4 are star-forming/gas-rich: LMC ($\mstar=1.5\times10^9\msun$) and SMC ($\mstar=4.6\times10^8\msun$) around the MW, LGS 3 ($\mstar=9.6\times10^5\msun$) and IC 10 ($\mstar=9\times10^7\msun$) around M31.  At $\mstar<8\times10^7\msun$, 50 of 51 satellites are quiescent, and at $\mstar<9\times10^5\msun$ \emph{all} are quiescent.
