Adult Fly-C62.8LZ Type • The lower abdomen of the fly was completely marked with blue stain. • We believe that this shows the neural pathways within the leg muscles of the fly. • The diagram next to our images shows the muscle development that occurs within Drosophila.

Larva-C62.8LZ Type • In adult flies the C62.8LZ Type had highlighted regions in the abdomen that linked to the legs at one point. • In the larva the C62.8LZ has the stain in areas where the legs begin to develop as well as in what appears to be a neural pathway from the head of the larva to the anus. • The C62.8LZ Type is stained mostly in motor neuron pathways in the legs and in some other areas of the body in both the adult fly and larva.

Larva-en Lac Z Type • For en Lac Z Type larva the midintenstine, or midgut, was the part most stained. • When compared to the picture on the right of our pictures one can see how in both pictures the larva’s intestines are exposed and stained a blue/purple color.

Larva-C362.14 UAS1 Type • The part of the larva stained for this type appears to be the salivary glands. • On each side of the larva there is a sac that is clearly stained in blue, and that sac is located at the same region as the salivary glands in Drosophila. • When compared to the highlighted salivary glands in the three larvae in the picture on the right, it appears as though salivary glands are clearly stained in both pictures.
