Third instar larvae expressing banEY09041 under the control of Scer\GAL4Pxn.PS have an increased number of sessile hemocytes. The number of hemocytes in circulation is similar to wild type. The dorsal sessile hemocyte department is not disrupted. Sessile hemocytes accumulate along the dorsal vessel but do not spread through the cuticle. The lymph gland is enlarged. Hemocyte shape is normal.
