Subfamily Heliconiinae.: A largely pantropical group, with one of the five tribes found in the Holarctic Region.
​
Tribe Acraeini: There are two Afrotropical genera contained within this tribe; Telchinia and Acraea, both represented at Semuliki. There are 138 described Afrotropical species within this tribe with 104 species recorded in Uganda. At Semuliki a total of 45 species from both genera have been recorded: 25 from the genus Telchinia and 20 species of Acraea, contributing to a third of the Ugandan species total.
Genus Cymothoe: There are 15 species of the Afrotropical genus Cymothoe so far recorded at Semuliki from a.continent total of 78 (Williams, 2018) and a Ugandan total of 17 (Williams, 2015) or 90% of Uganda's total. The two Ugandan species not being recorded at Semuliki being C. distincta and C. indamora, but with both these species being recorded either in the Ituri Forest or Semliki Valley (Ducarme, 2018) it is a distinct possibility that they will also be found in Semuliki. Only three species are frequently sampled in traps and these are C. sangaris, C. cyclades and C. confusa. This genus has been categorised into clades nd the most commonly trapped species C. confusa had a distinctly clumped distribution within Semuliki. Species from this genus were observed more in the forest midstorey as compared to the preference of the forest floor for the genera Bebearia, Euphaedra and Euriphene.

FAMILY PAPILIONIDAE
Subfamily Papilioninae
A comprehensive and recognised stable phylogeny for the genus Papilio has been an ongoing problem and debated from a number of studies over the last 40 years. The most recent research has created a time-calibrated species-level Papilio molecular phylogeny producing a reference framework (Condamine et al., 2023). From a total of approximately 600 species within this subfamily, there is a global total of 235 Papilio species of which 60 occur within the Afrotropical region. Afrotropical species have been split into four subgenera, 22 species being recorded in Uganda. There is a global total of 100 Graphium species, of which 41 are found within the Afrotropical region and 12 within Uganda. Within the park there have been 19 species from the two genera recorded at the park; Papilio with 14 species and Graphium with five. Being nectar feeders they were never found within traps and none of the species recorded within the park could be described as common and generally would be found within the forest fringes.
Genus Graphium
The five species so far recorded at Semuliki are G. policenes, G. leonidas, G. antheus, G. angolanus and G. ucalegon. There are a number of subgenera within the genus, with only one occurring in the Afrotropical region - Subgenus Arisbe. This subgenus is divided into a number of species-groups or clades.

Genus Papilio
Afrotropical species are divided into four subgenera: Papilio, Princeps, Druryia and Nireopapilio. The 14 species recorded at Semuliki described or shown below have not been clumped within the four newly described subgenera.

Papilio dardanus is categorised into a number of subspecies (possibly around 13) from male traits. The two subspecies found at Semuliki are P. dardanus dardanus and P. dardanus meseres. Six forms have been described within the subspecies, three of which are found at Semuliki f. hippocoon, f. planemoides and f. trophonissa (waiting on field image).
