The butterflies and moths (Insecta: Lepidoptera) are common insects, well known to everyone with high distribution in the world, which distinguish other insects by having scales on the wings from (Triplehor and Johnson, 2005). The larvae of most species of this order can feed on plants and fabric materials, being an important phytophagous pest for agriculture with high economic importance. While, some adult members of this large group of insects, especially coloured wing butterflies [Lepidoptera as one of the largest inset orders after Coleoptera, with more than 157000 species (Zhang, 2011)] are introduced as an excellent and beautiful model in natural history museums that can be attractive for visitors. The zoological specimens (e.g. butterflies and moths) as valuable heritage are presented for improving visitor’s biology knowledge. Natural history museum of Bu-Ali Sina University, Hamedan, Iran as one of important reginal tourism destinations, was typically ornamented with more than 8000 butterfly and moth specimens (mostly butterflies which are endemic to Iran) belonging to different families such as Hesperiidae Latreille, 1809; Nymphalidae Rafinesque, 1815; Lycaenidae Leach, 1815; Pieridae Swainson, 1820; Papilionidae Latreille, 1802; Saturniidae Boisduval, 1837; Noctuidae Latreille, 1809; Geometridae Leach, 1815; Sphingidae Latreille, 1802; Sesiidae Boisduval, 1828, that it plays a direct role in the presentation quality in increasing visitor’s satisfaction (~ 80%).
