Beat-Va _L but not Beat-Va _M neurons display caspase activation during metamorphosis. (A–D) Beat-Va neurons genetically labeled with mCD8::GFP and stained for cleaved Dcp-1 at wL3 (A), 2 h APF (B), 4 h APF (C), or 6 h APF (D). Right, A3–A7 lateral and medial cells from each hemisegment (L = left and R = right hemisegment) are magnified and shown as a single plane image on the right of each full VNC image. Scale bars are 20 µm in population images and 5 µm in the magnified view.
