Mauritian tomb bat (Taphozous mauritianus)

Identification pointers

This bat can be easily recognised when roosting by its alertness and crab-like behaviour when crawling sideways on a vertical wall. The fur is greyish above with pale white or cream below, with the white just touching the chin where a dark spot is present in males. The face is relatively hairless and ears are usually held flat against the head, which is lifted from the roosting wall in a lizard-like fashion when disturbed. Wings are pointy and narrow with light-coloured membranes; they have a fast flying pattern, keeping low over grass veldts or open spaces. Forearm length is 60-66 mm and its mass is approximately 27-36 grams.

Roosting habits

They don’t roost inside roofs or dark hollows as most insect-eating bats do, but are rather found to roost on the outside of walls under the eaves of a roof or in large tree trunks, rondawels and the trunks of Chinese fan palms and royal palms. Roosting colonies are generally small groups of about 5 bats though they may occasionally grow to about 30 individuals. They appear to be constantly vigilant and awake while roosting. Seasonal migrations are suspected but not proven, and the migration locations are unknown.


Two distinct birth periods are present: November - December and February – April, when a single young is born per birth period.


Mauritian tomb bats are moth specialists, but will also feed on flying termites and other insects.

Our box have a spotted eagle owl! We stay on a smallholding in the Chancliff area, Krugersdorp and discovered that our recently serviced owl box, has a long awaited inhabitant! So glad and thankful to have the privilege of sharing our piece of nature with hopefully a breading pair soon! Have to tell you the bats are also happily occupying their box!

Brilliant service from hugely knowledgeable installers at our home in Harties this morning. We are thrilled with our new bat and owl boxes and sure the residents of these will be too! Excellent to know that EcoSolutions also monitors numbers and patterns of the owls in perpetuity. Thank you!
