FIGURE 4 in Biology of the Afrotropical Sepedonella nana (Diptera: Sciomyzidae), whose larvae feed only on freshwater Aulophorus furcatus (Oligochaeta: Naididae)

FIGURE 4. Feeding behaviour of Sepedonella nana larvae (predator) on Aulophorus furcatus oligochaete (prey). A, thirdinstar larvae (L3) attacking and eating A. furcatus inside of their tube. B, assemblage of A. furcatus attacked by different instarlarvae of S. nana. C, naked A. furcatus. D, A. furcatus escaping the assaults of the sciomyzid larva moving back out at the end of its tube. E, details on duration (in days) of immature instars and total life cycle. L1, L3, first- and third-instar larva.
