We study numerically a prototype equation which arises genetically as an envelope equation for a weakly inverted bifurcation associated to traveling waves: The complex quintic Ginzburg-Landau equation. We show six different stable localized structures including stationary pulses, moving pulses, stationary holes and moving holes, starting from localized initial conditions with periodic and Neumann boundary conditions.
