  We revisit previously developed analytic models for defect evolution and
adapt them appropriately for the study of semilocal string networks. We thus
confirm the expectation (based on numerical simulations) that linear scaling
evolution is the attractor solution for a broad range of model parameters. We
discuss in detail the evolution of individual semilocal segments, focusing on
the phenomenology of segment growth, and also provide a preliminary comparison
with existing numerical simulations.
