ab TEM images showing the merger of the long and short rostral rod in H. Note the newly developing long rod and the fully differentiated short rod in A. c Formation of the short rostral rod in G and the formation of the subrostral process in F, note the bundles of actin filaments that are located under the microvilli. d TEM image of the formative site showing the fully differentiated long rostral rod in J, developing long rod of H, formation of the short rostral rod in G, formation of the socket in F–E, and the tip of the rostrums in A3. F1–F3 follicle cells, CB chaetoblast, arrow heads mark the adluminal adherens junctions, ab actin bundles
