Third instar larvae expressing CG15771EP1405 under the control of Scer\GAL4Pxn.PS have a normal number of sessile hemocytes. The number of hemocytes in circulation is also similar to wild type. The dorsal sessile hemocyte department is disrupted. Sessile hemocytes do not accumulate along the dorsal vessel or spread through the cuticle. The lymph gland is enlarged. Hemocyte shape is normal.
