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 PIERIDAE
Of the four subfamilies comprising this family, three are found within the Afrotropical realm: Pierinae, Coliadinae and Pseudopontiinae. All three subfamilies have species records found at Semuliki with a total of 41 species being recorded (Terias brigitta, Leptosia hybrida, Mylothris agathina, Belenois sudanensis, B. subeida, Colotis aurigineus, C. evarne and C. danae ) recently added since the published species list (Forbes, 2018). This represents over 40% of the 96 species recorded in Uganda (Davenport, 1996) but considerably less than the 83 species recorded by Ducarme (2024) for the Ituri Forest and DRC Semliki Valley.

Subfamily Pseudopontiinae
Comprised of only one genus, Pseudopontia which comprises five species.
Genus Pseudopontia. A purely Afrotropical genus, only one species has been recorded at Semuliki, Pseudopontia mabira. A species with a distribution confined to Uganda and the DRC.

Subfamily Coelidinae
A global group of which three genera have species recorded in the Afrotropical region: Colias, Catopsilia and Eurema. The single Colias species, found in Uganda, Colias electo is commonly restricted to submontane and montane habitat.
Genus Catopsilia. Of the two Afrotropical species within this group of six species, one is found throughout sub Saharan Africa, Catopsilia florella with the other species being confined to Madagascar in the Afrotropical region, but it is also found in Reunion and Mauritius.

Genus Terias (formerly Eurema). A taxonomic change was proposed by Zhang et al. (2021). Using genome sequencing they concluded Eurema (Hübner, 1819) was paraphyletic with Pyrisitia (Butler, 1870). To rectify this issue and restore monophyly, they chose to keep Pyrisitia as a genus and treat the Old World (Afrotropical) clade, currently placed in Eurema, as a distinct valid genus. Terias (Swainson, 1821) was then its oldest available name and therefore adopted. Terias is a pantropical genus with eight species recorded within the Afrotropical region. Seven species have been recorded in Uganda and also in the Ituri Forest of the DRC and the savannah habitat of the DRC Semliki Valley. Six species have so far been recorded at Semuliki: Terias brigitta has been recorded since publication of the species list (Forbes, 2018). T. mandarinula has been recorded within the DRC Semliki Valley and will more than likely occur at Semuliki National Park. Colour intensity of males in this genus is generally greater, while there is also considerable variation within species and associated seasonal variation.

Subfamily Pierinae
A large group of 222 species split into six tribes, with all species represented in the Afrotropical region. Four of the tribes are represented at Semuliki: Pierini, Teracolini, Leptosiaini, and Nepheroniini.
Tribe Leptosiaini
A tribe containing eight species, seven occurring in the Afrotropical region. Five species have been recorded in Uganda (and also in the adjacent DRC Semliki Valley and Ituri Forest) but only four species have so far been recorded at Semuliki (Leptosia hybrida being a new addition). The species so far unrecorded at Semuliki is Leptosia marginea.
Genus Leptosia. The four species recorded at Semuliki are Leptosia nupta, L. alcesta, L. wigginsi and L. hybrida. These are very delicate to handle and photograph in the field, without damaging the specimen and so opportunities for good images are limited.

Tribe Pierini
Of the many genera described within this tribe, four are recorded at Semuliki: Mylothris, Belenois, Dixeia, and Appias. The four genera recorded at Semuliki are consistent with what has been recorded in the Ituri Forest of the DRC.
Genus Mylothris. This genus has had a taxonomic revision (Warren-Gash, 2020) and species can roughly be placed within six geographical zones. Semuliki National Park is located within the East-Central division which includes the DRC and southern areas of South Sudan and the CAR. The Albertine Rift provides an eastern border for this division. There are five clades within this genus and the four species recorded so far at Semuliki are found within three different clades: Mylothris rhodope in the rhodope clade, M. continua in the hilara clade and both M. chloris and M. agathina in the agathina clade. Four species have been recorded at Semuliki and this is in comparison to the 19 species recorded from the Ituri Forest and DRC Semliki Valley.

Genus Appias. Not an exclusively Afrotropical genus with a total of six species with four recorded in Uganda. So far only three species have been recorded at Semuliki: Appias phaola, A. epaphia and A. sabina. The Ugandan species not recorded at Semuliki is A. sylvia, although it has been recorded in the Ituri Forest.​

Genus Dixeia. This genus, solely from the Afrotropical region comprises ten species, one of which has been recorded at Semuliki, Dixeia pigea, contributing 25% of the species recorded within Uganda. Not so far recorded at Semuliki are Dixeia dixeyi, D. doxo and D. orbona. The species Dixeia dixeyi has been recorded both within the Ituri Forest and the DRC Semliki Valley so would be expected at Semuliki.

Tribe Nepheroniini
Of the two genera described within this tribe, only one is found in the Afrotropical region: Nepheronia.
Genus Nepheronia. An Afrotropical genus comprising only five species, with four being recorded in Uganda and all four have been recorded at Semuliki. The fifth species being an endemic of Madagascar, Nepheronia pauliana.​

Tribe Teracolini
A predominantly Afrotropical tribe which includes six genera from the region of which three are recorded at Semuliki: Colotis, Eronia and Afrodryas.
Genus Colotis. An Afrotropical genus comprising 41 species, with 24 being recorded in Uganda but only seven (Colotis evarne, C. danae and C. aurigineus have been recorded since the species list was published) so far recorded at Semuliki. 11 species have been recorded from the DRC Semliki Valley, suggesting targeted sampling of the savannah patches near the Semliki river and near the offices at Sempaya, will contribute to further species being recorded.
