When you first think of threatened or endangered species, you might immediately picture Rhinos, African Wild Dogs, Pangolins, or even some other charismatic bird, reptile, or amphibian. However, did you know that many insect species in South Africa are also threatened? Most of these insects are found in in the Western Cape, particularly in the Fynbos biome. Among these, butterfly and beetles receive far more attention than any other insect group. All 23 Cape stag beetle species (family Lucanidae, genus Colophon) are currently threatened, primarily due to climate change, habitat destruction, and illegal poaching – yes, even insects are poached!
Regarding butterflies, the most threatened species belong to the families Lycaenidae (coppers, opals and skollies) and Hesperiidae (skippers and rangers). These butterflies are all relatively small and inconspicuous, with tiny, isolated populations scattered throughout the landscape. Some threatened butterflies inhabit areas smaller than 100 square meters! Habitat destruction, mainly caused by alien invasive vegetation and landscape transformation, poses a significant threat to these species in the Western Cape.
To help conserve these butterflies, the Drylands Conservation Programme, in collaboration with Bionerds, has launched projects funded by Disney and Table Mountain Fund. These initiatives aim to protect six butterfly species in the Lycaeinidae family: the Moorreesburg Opal (Chrysoritis thysbe schloszae), Dickson’s Copper (Chrysoritis dicksoni), Bearded Skolly (Thestor barbatus), Dickson’s Skolly (Thestor dicksoni warren), Kaplan’s Skolly (Thestor kaplani), and Strutt’s Skolly (Thestor strutti). All of these are listed as Critically Endangered, and their populations are rapidly declining. Protecting our threatened butterflies requires safeguarding their habitats, which includes habitat protection activities such as clearing alien invasive vegetation. While physically protecting habitats is crucial, educating the public is equally important!
One key component of the project is environmental education aimed at schools near the six butterfly populations. Bionerds has created a colourful, interactive booklet titled “Threatened Butterflies of the Western Cape” for learners from grades 4 to 7. On September 19, Field Officer Renier Basson visited W.F. Loots Primary in Wolseley to present on the ecological importance of butterflies and the threats they face. The Strutt’s Skolly, found in the area, was a focal point of the presentation. Renier began by explaining, “What is a butterfly?” covering topics from taxonomic classification and morphology to metamorphosis, pollination, and threats. The 51 learners from grades 5 and 6 were engaged and inquisitive, asking numerous questions.
After the presentation, Renier handed out the booklets , and the students eagerly participated by reading important sections aloud. They also answered questions from the first few pages, which sparked curiousity and encouraged them to share their newfound insights. Questions included broad topics like “What do adult butterflies eat?” and “Where do butterflies lay their eggs?” To further engage the students, Renier showcased pinned and framed insects. With five display boxes filled with insects, the learners were divided into groups to maximise their time exploring each box. They had to identify butterflies in the boxes, which proved challenging as some moths closely resemble butterflies. The students were also encouraged to ask questions about the insects they observed. The excitement on their faces as they received new boxes was priceless!
Incorporating environmental education for children into all conservation programmes is essential. Children are curious, enthusiastic, and passionate about nature, making them open to listening about the natural world. Start them young!
