Genus Melanitis: All three of the Afrotropical Melanitis species have been recorded at Semuliki: M. ansorgei, M. libya and M. leda. M. leda is commonly sampled in the fruit traps while M. ansorgei and M. libya were rarely encountered. M. ansorgei also appeared to be site-dependent which is often due to small-scale spatial differences in environmental conditions that either promotes or inhibits populations, conditions which are often observed within the forest. M. libya and M. leda are seasonally polymorphic and M. leda forms are nicely illustrated by Williams (2020). A recent taxonomic change has included M. ansorgei within a new monobasic (single species) genus -Ducarmeia.
