During the last 150 years, insect collectors from abroad continually came to Taiwan and collected large quantity of insect specimens and deposited in their museums or the related research organizations. Type specimens and voucher specimens play a very important role in taxonomic works and related applied biological research works. So collecting the information including literatures and images of the type specimen is a very urgent work in entomological research in Taiwan. This project will spend five total years and aims at searching out insect type specimens including holotypes, syntypes, cotypes etc. from surveying literatures, having collaboration with related museums or institutions abroad, and visiting the related organizations taking the images of type specimens and then building up a type database for public access.
