Temminck's Myotis is a bat recorded from Liberia, Ethiopia and the Democratic Republic of the Congo south to South Africa. A study at five South African sites found both aquatic and terrestrial insects in its diet.
A Southern African field guide describes the upperparts as coppery brown and the underparts as pale brown with a coppery-red wash. The ears and wing membranes are reddish brown, and the long ears have rounded tips.
At five sites in South Africa, fecal analyses and dietary tracers found both aquatic and terrestrial insects in the diet. Aquatic insects contributed more at sites near large bodies of calm or slow-flowing water, so the diet mix differed among sites.
