Biology

The habitat consists of afromontane forests usually at altitudes above 1,800 metres (5,900 ft).

Notes on the biology of acuminatus are given by Larsen, T.B. (1991) and Kielland, J. (1990). [5] [6]

The larvae feed on Allophylus species (including A. alnifolius, A. chirindensis, A. abyssinicus, A. chaunostachys and A. africanus) and Bersama abyssinica.
