The land usage change represents a change in the landscape composition at a larger scale that can generate a change in the composition, distribution and diversity of fauna and flora species. Major crops are attractive for pests species that affect production and generate economic losses. The larva of Opsiphanes cassina Felder is a pest that affects oil palm crops and can be disastrous to it if it is not controlled. Due to this, it was decided that an investigation of the landscape composition may affect the abundance of the adult specimens of the species. For this it was realized an ecosistems identification adjacent to a Elaeis guineensis crop in Sabana de Torres in Santander to establish a butterflies sampling with the purpose of compare if there is any difference in the number of butterflies in the crop center in comparison with other plots adjacent to other ecosistems. It was found a bigger number of butterflies and a larger palm damage at the crop center tan at the external plots however there is no significative difference between the influence that exert the different adjacent covers. This confirms that an extensive crop with low diversity of adjacent ecosistems is more susceptible to pests attacks than the crops surrounded by less homogeneous landscapes.
