This species has been recorded from many hosts in the Neotropics including: Terminalia sp. ( Combretaceae), Hevea brasiliensis, Ricinus communis ( Euphorbiaceae), Albizia gummifera, Dioclea megacarpa, Tetrapleura tetrapetra ( Fabaceae), Theobroma cacao ( Malvaceae), Swietenia sp. ( Meliaceae), Maesa rufescens ( Primulaceae), Citrus aurantifolia ( Rutaceae) (Wood and Bright 1992). African hosts are listed in Schedl (1963: 289). Wood reported collecting the species from dying branches 3-7 cm in diameter as well as large boring in large limbs and stumps (Wood 1982, 2007) but it has also been collected in twigs as small as 1 cm in diameter.
