Abstract

This study was divided into two parts, which were the documentation of host plant feed by Lepidoptera and Lepidoptera rearing to records its life cycle. The study sites include UMS Hill, Kawang Forest Reserve and Danum Valley Conservation Area. Direct searching and quadrat sampling were applied in collection of sample which include egg and larva of Lepidoptera while rearing was completed in captive. The favourite host plant types for Lepidoptera are herbaceous and woody plants which accounted 37% one. Next, tree occupied 11% while shrub occupied 10% among all plant types. The lowest rank is 5% for woody climbers. Out of 11 families, 2 were monocotyledons plants while 9 were dicotyledons plants. All of the Lepidoptera are host specificity indicated by the comparison of sample collection with the past documentation are from the same plant Family. Lepidoptera are either monophagous or oligophagous. The morphology and behaviour changes in different stages within the life cycle are recorded. In this study, many specimens were collected as predicted to become Lepidoptera in future but failed to survive. Few problems such as shortage of food resources, changing of weather and climate, limited rearing space and disappearance have to be solved to improve the successfulness of butterfly rearing in captivity. These findings contribute as the foundation on conservation effort of Lepidoptera.
