Trophic associations of lepidopteran larvae have been formed from a long period of evolution. The larva of Oecophoridaecan keep being concealed with several strategies. They may be sheltered within a web or hidden under bark or deadwood, or inside leaves rolled by them. Sometimes they bore stem or trunk or burrow under bark or hide in soil. In addition,they can also be found in very diverse and specialized microhabitats. This study was to assess the ancestral characterstate of microhabitat and larva sheltering strategy within the phylogenetic relationship of Oecophoridae to understand theirevolutionary transition and the adaptation of larva to microhabitats using sheltering strategies. Also, it is to investigatethe historical biogeography and evolution of the family Oecophoridae and related higher taxa for understanding their globalradiation and distribution.
