Butterflies arernconsidered as one of the most studied groups of insects and are termed asrnbio-indicator. Hence the total number of butterflies of a certain region shouldrnbe well documented. In the field survey of Pablakhali Wildlife Sanctuary andrnMadhabkunda Eco Park, we found two butterflies which are new to Bangladesh,rnaccording to the most recent checklist. The Plane (Bindahara phocides,rnFabricus) was recorded from Pablakhali Wildlife Sanctuary and Orange Tail Awl (Bibasisrnsena, Moore) from Madhabkunda Eco Park. Though Plane was recorded byrnGladman (1947) and Emmet (1948) but Larsen did not find this species. Inrnaddition, no one ever recorded Orange Tail Awl from this region.
