This study showed that changed environmental conditions, such as a disturbed forest edge, as well as additional human influences (mowing, music, etc.) can affect butterfly assemblage and richness. As stated earlier, Lepidopteras are warning signs for environmental alterations since they are influenced by temperature changes, light and climate changes, and the alteration of host plant diversity (Hogsden and Hutchinson 2004). However, a fit habitat with little disturbance is necessary for continued species diversity within rainforest areas. Fortunately, Costa Rica has been very assertive in designating rainforest land as national parks and refuges in order to slow down deforestation and save exotic as well as endemic species. Nevertheless, it is important to frequently monitor both forest and forest edge habitats in order to have continuous and comparable data and being able to correlate between specific vegetation and geophysical factors within these two habitats. Furthermore, future butterfly studies in different seasons would also be recommendable with attention to butterfly species, species behavior, as well as host plants. Tropical butterflies are very difficult to identify and observe since there is a large variety of them, therefore it is important to perform further studies and obtain better knowledge in this field to protect and preserve important rainforest species.
