Third instar larvae expressing Rpn8EP687 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. Inappropriate targeting of hemocytes is seen, but sessile hemocytes do not accumulate along the dorsal vessel or spread through the cuticle. The lymph gland is not enlarged. Hemocyte shape is normal.
