Effect of prey density on the consumption and
predation rate
For each H. ephippiger nymph, L. natalensis snails (small,
medium or large) were supplied at densities of 5, 10, 15, 20 and
25 snails. Predators were allowed to prey for a period of 24 h.
Five replicates for each prey density were performed to determine
the mean number of prey consumed/day and subsequently
the predation rate.
