Lactating tsetse flies models for lactating mammals?

An unprecedented study of intra-uterine lactation in the tsetse fly reveals that an enzyme found in the fly’s milk functions similarly in mammals, making the tsetse a potential model for lipid metabolism during mammalian lactation. Better yet, reduced levels of this enzyme led to poor health in offspring, leading the authors to suggest that targeting it could help decrease the tsetse population in Africa and so reduce the incidence of sleeping sickness.
