Distribution

Distribution_of_Ficus_natalensis_natalensis

From north-eastern South Africa to Uganda and Kenya.

Biology

Pollinators: Elisabethiella allotriozoonoides (Grandi), Elisabethiella socotrensis Mayr, Elisabethiella stuckenbergi Grandi, Alfonsiella brongersmai Wiebes, Alfonsiella longiscapa Joseph & Alfonsiella natalensis Wiebes, 1972. Four of these species: Alfonsiella brongersmai, A. natalensis, A. longiscapa and E. allotriozoonoides have been recorded together in the same fig crop in Uganda (Compton et al., 2009). Elisabethiella socotrensis often develops together  with E. stuckenbergi in the same fig in South Africa (Cornille et al., 2011).

Habitat

Forest (both wet and dry), and woodland in rocky places, up to an altitude of 2200m.
