All butterflies were individually marked on the underside of the forewing with felt-tipped pen according to trap location.
For large butterflies (e.g. Kallima limborgii, Bassarona dunya, Neorina lowii) each individual was marked with a unique number; smaller butterflies were given a location-specific mark.
All marked butterflies were then released back into the population unharmed. Euthalia spp.
and Tanaecia spp.
can only be identified reliably from male genitalia (Otsuka 1988) and were not identified to
19
species in this study and so were excluded from the analyses.
All other fruit feeding butterflies that were captured (and recaptured) were identified following Otsuka (1988).
