Abstract
Starspot lifetimes (to) are computed with the assumption that they are disrupted by the shearing effect of differential rotation and compared with observed lifetimes (to) for 40 spots on 17 different stars. The differential rotation coefficient (k) for each star is estimated from the range of rotation periods exhibited by its maximum wave amplitude (Δm). Small spots (rs<20°) die before they are disrupted (to < to) but larger spots are in fact disrupted by differential rotation (to= to).
