Dear Friends,
This is what we call BATABI LEBU (LEBU = any Citrus fruit) in Bengali. This plant doesn't need any special care to grow and its fruits are relatively cheap source of vitamins & minerals for villagers who can't afford to have an orange or an apple. I have heard that the fruit is beneficial to cure/recover from "jaundice".
Species : Citrus maxima (syn. Citrus decumana) (family : Rutaceae)
Date : 08/Feb/2012, 9.23 A.M. & 15/11/2011 (the fruit with the butterflies)
I also attach a photo featuring Common Baron (female) butterflies feeding on its partly rotten fruit.
Thank you & Regards,
Surajit Koley
