Recent ecological studies give so much attention to biodiversity and conservation. As some initiative on conserving biodiversity, naturalistic landscape designs are incorporated to various holiday destinations offering extreme sport adventures, promoting tourism as source of income while preserving natural habitat. However, it is not impossible that an alteration will be made from the original habitat or even frequent exposure to various anthropogenic activities that causes disturbances may seriously affect sensitive species. This study measured diversity of hawkmoths in two selected sites with different vegetation types: 1) the Mt. Hamiguitan ranges (Natural and protected forest) Ecopark (site 1), Camp 3 (Site 2), Black Mountain (site 3) and study area 2: Busay Garden and Spring Resort. The sampling was carried out using 500w bulb light trapping method powered by a portable generator. A total of 305 individuals representing 22 species of hawkmoth from both sites were recorded. Shannon-Weiner indicates that Hawkmoths were more diverse in Busay Garden and Mt. Hamiguitan site 1 where diversity index were the same with H’=1.258. They have the same diversity indexes, but they differ on species richness (Hmax= 1.301 for site 1, Hmax=1.342 for site 4) and evennes with J=0.9672 for site 1(Ecopark) and J=0.937 for site 4(Busay Garden).Diversity of hawkmoths increases as elevation increases except for site 3 (H’=1.161) where the elevation was higher than site 2(H’=1.06). Bray-Curtis Similarity Index of hawkmoth in Busay Garden and the Eco-park of Mt. Hamiguitan have shown high (73%) species similarity. The diversity of hawkmoths was high at lower elevations and the results suggests that developing gardens into having more diverse host plants may promote higher species diversity. Further study on its implications with wider coverage and longer sampling duration is recommended.
