In this note, we obtain a level based sequence of rooted caterpillars whose vertices are located
on the spines have equal number of attached leaves. We obtain the general formula of the level index of the
mentioned caterpillar and give a characterization of the level index of the caterpillar by the solution of a
difference equation.
