The relative error between $R_0$ and $R_{0nc}$ increases as the offset between larval and nymphal emergence increases. This error is exacerbated for low host density and low contact rates between ticks and mice because fewer ticks successfully feed by the end of the season which drives lower equilibrium tick sizes. $M=k(1-{\mu }_m/b)$ is the mouse population size, ${\gamma }_l$ and ${\gamma }_n$ are the contact rates between larvae and mice and nymphs and mice, respectively. All other parameter values are shown in Table 1
