Dracaena sp. ??

To me appears close to images at Dracaena terniflora Roxb. as per comparative images at Dracaena

Dracaena terniflora posted from Tripura and Kalimpong are actually D. elliptica Thunb. & Dalm., a widespread and variable species.

This is for your kind information please.

I was privileged to see some 50 Leopard Lace wing emerging from pupa in last two months. I observed

(a) Butterflies emerging in November and early December come out around 10AM and fly by 12PM or so. Number of males and females were evenly distributed.
(b) Butterfly emerging in December end and January were coming out  at about 1 PM and fly by 11AM on the next day. They were mostly male.

Attaching an image of a newly released male Leopard Lace Wing visiting flowers of Dracaena fragrans.
