Abstract: In this study butterflies were used in assessing re-vegetation as a way of biodiversity restoration at Wazo hill quarry. The Butterflies were used as indicator species because of their high sensitivity in ecosystems alteration. The study was done in two different areas each 4.8 acre, namely the re-vegetated and un-quarried areas. Butterfly sweep nets and Butterfly traps baited were used for Butterflies capturing. Thirty six (36) species of Butterflies were identified and voucher specimens were preserved in Kingupira Museum. Variation in species diversity was evaluated using diversity indices and tested using special t-test. Variation in Butterfly abundance in two study sites and in different habitats was determined using Kruskal-Wallis Test Statistic and Mann-Whitney U test statistic. The diversity of Butterflies was significant higher in re-vegetated site than in un-quarried site while the abundance difference in the two sites were insignificance The two sites varied in plants species diversity and level of succession, a condition attributed to variation in Butterfly diversity. The re-vegetated sites were recommended for aesthetic, education purposes and further studies on organisms.
