20 common insects found on Kilimanjaro

On Kilimanjaro, insects—invertebrates with exoskeletons and various features—live in abundance, especially in the rainforest zone. The various species and existence across Kilimanjaro’s varied terrain are evidence of the mountain’s tremendous geographical diversity. Though sometimes misunderstood, these microscopic marvels are essential to our ecosystem.  Kilimanjaro’s veritable insect kingdom reflects the diversity of its surroundings, ranging from helpful pollinators to annoying bugs and pests apart from Tse tse flies which thrive in many parts of northern Tanzania except Mount Kilimanjaro.

If you are wondering if there are spiders on Kilimanjaro, well, numerous spiders and other invertebrates, such as the Pterinochilus chordatus, or Kilimanjaro mustard baboon spider, can be found in the forested regions of Mount Kilimanjaro. This ancient tarantula may grow up to 2 inches in length and 6 inches in width across its legs. It is located in eastern Africa, ranging from Sudan to Tanzania. Since it can be aggressive, beginners are advised against owning one as a pet.

Their role in pollinating night-blooming plants ensures the continuation of various plant species. The varying wing patterns and colours of moths also contribute to their role in their respective ecosystems.

9. Termites

Termites, social insects that feed on wood and plant materials, are prevalent in the Rainforest and Montane Forest zones. Species like the Macrotermes bellicosus build complex nests and play a critical role in nutrient recycling. Their ability to break down cellulose-rich materials contributes to soil health and fertility. Termite mounds are often seen as prominent features in these ecosystems, showcasing their impact on the environment.

10. Crickets

Crickets, known for their long hind legs and characteristic chirping sounds, are found in the Rainforest, Montane Forest, and Heath zones. The Gryllus campestris and Acheta domesticus species are notable for their nocturnal behaviour and their role in the food web as prey for various predators. Their chirping, produced by rubbing their wings together, is a familiar sound in the evening hours, adding to the acoustic diversity of their habitats.

11. Grasshoppers

Grasshoppers, similar to crickets but generally larger with shorter wings, inhabit the Montane Forest and Heath zones. Species such as the Pseudopodisma flavescens are primarily herbivores, feeding on grasses and leaves. Their presence can indicate the health of grassy and shrubland areas, and they serve as a food source for various predators.

What is the importance of insects on Kilimanjaro?

Insects play a very important role in the ecosystems of Mount Kilimanjaro. Their importance can be highlighted through several key ecological functions:

1. Pollination: Many insects, such as bees, butterflies, and certain beetles, are essential pollinators. They help in the reproduction of various plant species by transferring pollen from one flower to another, which is vital for the production of fruits and seeds.
2. Decomposition and Nutrient Cycling: Insects like ants, beetles, and termites contribute to the decomposition of organic matter. They break down dead plants and animals, returning vital nutrients to the soil, which supports plant growth and maintains soil fertility.
3. Food Source: Insects are a primary food source for many animals on Kilimanjaro, including birds, reptiles, and small mammals. This helps sustain the food web and maintain biodiversity in the region.
4. Predation and Pest Control: Predatory insects, such as spiders and certain beetles, help control populations of other insects, preventing overpopulation and potential damage to plant life. This natural pest control is essential for maintaining ecological balance.
5. Soil Aeration: Insects like ants and beetles burrow into the soil, creating channels that allow air and water to penetrate more deeply. This aeration is crucial for healthy soil and promotes root growth for plants.
6. Seed Dispersal: Some insects contribute to seed dispersal, either by carrying seeds to new locations or by facilitating the growth of plants that depend on insect interactions for seed dispersal.
7. Indicators of Environmental Health: Insects are sensitive to changes in their environment, making them good indicators of ecological health. Studying insect populations can provide insights into the effects of climate change, habitat loss, and pollution on the mountain’s ecosystems.
