Two Common but Harmless Snakes of the Kisii Highlands
The Kisii Highlands, with their lush vegetation and mild climate, are home to a variety of wildlife, including several snake species. While many people fear snakes, not all of them are dangerous. In fact, some are completely harmless and play an important role in controlling pests.
Today, we’ll discuss two common but non-venomous snakes found in the Kisii Highlands:
- The Spotted Bush Snake (Philothamnus semivariegatus)
- The Herald Snake (Crotaphopeltis hotamboeia)
1. Spotted Bush Snake (Philothamnus semivariegatus)

Appearance
The Spotted Bush Snake is a slender, graceful snake with a bright green or bluish-green body adorned with black spots or bars along its back. Its belly is usually yellow or white, and its large eyes give it excellent vision.
Habitat & Behavior
This snake is arboreal, meaning it spends most of its time in trees and shrubs. It is diurnal (active during the day) and incredibly fast-moving. When threatened, it may inflate its throat to appear larger but rarely bites.
Diet
It primarily feeds on frogs, lizards, and small birds, making it beneficial for natural pest control.
Is It Dangerous?
No! The Spotted Bush Snake is non-venomous and completely harmless to humans. It is shy and will usually flee rather than confront people.
2. Herald Snake (Crotaphopeltis hotamboeia)

Appearance
Also known as the Red-lipped Snake or White-lipped Snake, this species has a distinctive white or yellowish upper lip, giving it a unique “smiling” appearance. Its body color varies from gray to olive or brown, sometimes with faint speckles.
Habitat & Behavior
The Herald Snake is nocturnal (active at night) and often found near water sources, grasslands, and forests. It is a ground-dwelling snake but can climb if necessary. When disturbed, it may flatten its neck (like a cobra) and strike, but it is not aggressive.
Diet
It mainly preys on frogs, toads, and sometimes small rodents.
Is It Dangerous?
While it has mild venom (rear-fanged), it is not harmful to humans. Its bite may cause slight irritation, but it is not considered medically significant.
Why These Snakes Are Important
Both the Spotted Bush Snake and the Herald Snake help maintain ecological balance by controlling populations of frogs, lizards, and insects. Instead of killing them, it’s best to appreciate them from a distance and let them continue their role in nature.
What to Do If You See One?
- Do not panic – they are not a threat.
- Observe from a distance – they will likely move away on their own.
- Do not kill them – they are beneficial to the environment.
Next time you spot one of these beautiful creatures in the Kisii Highlands, remember: they’re more afraid of you than you are of them!
