Ukasi Hill: Yellow-Haired Fly Abode

Garissa is approached on a good road, the A3, from Nairobi through Thika and Mwingi, which runs across the northern frontiers of Kitui and Tana River Counties, forming the primary line of communication to its capital town of Garissa, 369 km away. Owing to the comparatively low rainfall and to the indigenous practice of overgrazing, the landscape beyond Thika is mainly of the thick thorn-bush type with little grass. Around Mwingi, 127 km east of Thika, where the road crosses the River Kanginga, the ground slopes away eastwards with a handful low-lying hills.

Rising abruptly from this plain are three modest hills – Endau (4,387 ft), Engamba (3,100 ft) and Kandelongwe (1,570 ft). This featureless plain, on which are wide-spaced valleys and scanty inselbergs, continues eastwards and north-eastwards until Garissa Town is reached, set along on its western border. Ukasi, where the Ukasi Hill is found, is a further 61 east of Mwingi. It lies just beyond Ukasi Police Station. This craggy upland is more impressive for what it contains than the site itself. The modest hill earned its fame from its eerie and rather bizarre residents.

Unique to the unassuming 120 ms high Ukasi Hill is that it is home to one of the rarest and oddest looking flies in Kenya: Scientists first came across the yellow-haired fly in 1933 and again in 1948. Since then, at least half a dozen expeditions have visited the location to find this odd insect dubbed as the terrible hairy fly – Standard Media. This bizarre fly, unable to fly and partial to breeding in bat doings, is thought to live only in the dark, bat-filled cleft on the isolated Ukasi Hill. It has peculiar non-functional wings resembling miniature belt straps and mingy eyes.


Around Kenya are a selection of natural landmarks, cultural shrines, architectural oddities, and technological installations that offer incredible, almost surreal experiences that can make you feel as if you’ve stepped into another world. Hauntingly beautiful to some, eerie sights for others, and still, for others, down right strange, these site provide unique experiences for adventurous travelers.


Kitui County is a hidden gem for travelers seeking adventure, culture, and nature. With better infrastructure and marketing, it could become a key destination in Kenya’s tourism map. Known for its arid and semi-arid landscapes, rich Kamba culture, and untapped tourism potential, it is home to many unique attractions, hillscapes, scenic rock formations and valleys ideal for hiking and photography.
