  In this paper, we present a two-species Vicsek model, that describes
alignment interactions of self-propelled particles which can either move or
not. The model consists in two populations with distinct Vicsek dynamics that
interact only via the passage of the particles from one population to the
other. The derivation of a macroscopic description of this model is performed
using the methodology used for the Vicsek model: we find out a regime where
alignment in the whole population occurs. We obtain a new macroscopic model for
the densities of each populations and the common mean direction of the
particles. The treatment of the non-conservativity of the interactions requires
a detail study of the linearised interaction operator.
