Distribution

Ficus sycomorus Distribution Ficus sycomorus Madagascan Distribution

From South Africa to Senegal and the Arabian Peninsula and Madagascar. Planted for cultivation in Egypt, Israel and Syria.

Biology

Pollinator: Ceratosolen arabicus Mayr; Ceratosolen galili Wiebes is a cuckoo.

Habitat

In woodland, near streams.

Frugivores

Birds, bats and monkeys feed on the ripe figs facilitating seed dispersal.

Insects

The larval stages of a variety of insects feed on the leaves or figs of Ficus sycomorus including caterpillars of butterflies and moths, some of which have developed remarkable strategies to overcome the sticky latex contained in the leaves. Other insect larvae bore into the branches feeding on the wood or suck sap from leaves or figs.

Fig_tree_borer

Beetle larvae of the Fig tree borer beetle Phyrneta spinator (Coleoptera) bore into the branches and trunks often targeting water stressed, damaged or older trees

Leaf Hopper bugs Hilda patruelis (Hemiptera) suck the sap  from figs and are tended for honeydew by pugnaceous ants Anoplolepis custodiens or Pheidole megacephala. By patrolling figs with bugs the ants reduce the impact of parasitoid fig wasps (which oviposit through the fig wall) on pollinator larvae and hence increase the reproductive fitness of the tree.
