Taiwan has more than 80 species of lymantriid moths (members of the family Lymantriidae), which do secrete poisons, but few of them are easy to find in the wild. Although Yen Sheng-hung has caught countless insects over the years, there are many rare lymantriid moths which he would like to study but simply cannot find.
