The fatty acid (FA) compositions for total lipids from fat body, hemolymph and flight muscle of the armyworm moths, Mythirnna separata , at rest and after tethered flight for 1 h were determined by GC and GC‐MS. The composition in these tissues comprises myristic acid (1%‐2%), palmitic acid (more than 35%1, palmitoleic acid (9%‐11%), stearic acid (less than 1% ), oleic acid (about 32%), linoleic acid (12%‐17%) and linolenic acid (3%‐6%). After flight, FA level in the fat body, compared to that at rest, shows a significant decline at about 20 μg/mg tissue.h ‐1 ; the concentration of FAs in hemolymph rises evidently, but change of FA content in flight muscle appears to be small. From the changes of proportional composition of FAs in fat body, hemolymph and flight muscle, it is found that the FAs selectively utilized for flight in flight muscle are predominantly the palmitic acid and oleic acid.
