After looking at your photos I think that you are seeing the imaginal
component of the gut, that is, those cells that will form the adult gut
itself. These are scattered throughout the larval gut in the regions
that are giving you the brightest fluorescence. I am assuming the blue
photos are DAPI, HOECHST 33258 (bisbenzimide), our some other chromosome
