Summary The total fatty acid fraction of the tachinid fly, Phryxe caudata, contains mainly oleic and palmitic acids which together account for nearly 75% of all fatty acids present. There are no noticeable changes in proportions of individual fatty acids during larval development, although there is a considerable increase in total fatty acid concentration. The way each fatty acid accumulates is mathematically described. During nymphal life as well as in the newly emerged imago, the relative composition of the larva is maintained in spite of an increase of linolenic and eicosenoic acid concentration. Pupal life is characterized by a large drop in levels of total fatty acids.

Abstract Les acides gras totaux du Diptère Tachinaire, Phryxe caudata, ont été analysés au cours des développements larvaire et pupaire. La teneur en acides gras totaux varie de façon importante au cours du développement, mais les concentrations relatives varient peu: les acides oléiques et palmitiques représentent près de 75% des acides gras totaux.
