Scanning electron microscopy of the fourth and first instar larvae of Migonemyia migonei.
(A) observation of first (1st) and fourth (4th) instar larvae, showing the number of body segments and caudal filaments, dorsal view, cf—caudal filaments; h—head; pt—prothorax; mst—mesothorax; mtt—metathorax (Scale bar: 200μm). (B) higher magnification of the surface of the caudal filament showing pores implanted between non-parallel, interconnected and overlapping ridges, rdg—ridges; po—pores (Scale bar: 5μm).
