Abstract: Drosophila melanogaster is a model organism in genetics thanks to the compactness of its genome and its
relative simplicity. Recently, certain developmental patterns in Drosophila have been studied by mathematical
models, with the aim of gaining deeper and quantitative insight into the morphogenesis of this insect. There
is a need for accurate dynamical of the epithelial cell structure and organization within the fly wing, to further
the understanding of a phenomenon known as planar cell polarity. The present study tackles the problem of
retrieving such a salient structure using classical tools of dynamical system theory embedded with network
and graph concepts. On the one hand the goal is to provide a visual detection and representation of the cell
packaging that is accurate and fine. Particular care is also put in obtaining a model of this structure, whose
