Horton plains where above picture was also taken. However he further says that it is occasionally
taken along roadsides of Haldummulla (3000ft) and found common at Galaha near Kandy .
According to him those taken below 4500ft are usually smaller than those
from the highest elevations. It is not uncommon in Sinharaja (Guide to Sinharaja - IUCN) and some other lowland wet zone forest areas (personal observations). Its larva feeds on leaves of Garnotia exaristata and Ischaemum timorense.

තල[Tala]/Talipot palm(Corypha umbraculifera)
Leaves of Talipot palm tree have been using
for writing since ancient times and it has a very restricted distribution
(1) and it is always associated with human habitations. So it is believed
that it was introduced to the Sri Lanka from India for the purpose of documenting Buddhist
sacred text and other writings. Flowering occurs when the tree is around 40
years old and most probably all the trees in the vicinity blooms with flowers simultaneously
possibly because they are of same age due to seed crop of same parent tree.
Other than for writing, leaves use for thatching, as umbrellas and for basket
and mat weavings.
(1) According to the Flora of Ceylon Vol 14
its distribution is limited to the narrow belt bordering northern wet and intermediate
lowlands [Molagoda, Warakapola, Mirigama, Gampaha Mathale, Gampola, Galewela]
and the eastern intermediate lowlands [Badulla, Ranwala, Godakawela]
