This story is from a place called Tumprong which is an hour's walk from Leek. Most of the Land there belongs to people from Tingvong, they come during the makkai (maize) plantation time, plant the makkais and go back to Tingvong.
An old couple used to live there at the time. Every Makkai season the land owner [(Dawa and Ugen) brothers] from Tingvong used to find their makkai being eaten, when asked to the couple, they shrugged it off blaming the bear who comes down to eat makkai during the season. This happened for a long time.
The brothers were unconvinced with that story and decided to stay back and check who was the real culprit. They prepared their bows and arrows for the night, warned the old couple not to venture into that area. The old man decided to go and steal makkai anyways, so he wore his bear skin and went to the fields. Dawa realizing that there was someone there gives a first warning ordering if it were human to move away to which the old man replied with a loud roar. Ugen then gives a second similar warning to which he meets the same reply. After an initial discussion between the brothers, Dawa decides to shoot a warning arrow towards the creature. It goes straight and lands on the knee of the old man.
After a loud roar...the old man keeps going about filling his sack with makkais. Seeing this Ugen shoots another one, this one flies straight to the heart of the old man. The old man by now finished with his makkai business flees the scene and goes home bleeding profusely from the heart and his knee.
After arriving home he gently opens his bear suit, removes the arrow from his knee and tells his wife to make makkai soup, his favorite. Thereafter he removes the arrow from his heart, the heart comes out with it...he keeps it beside the fire and goes to sleep forever.
Legend has it that whenever travelers pass through that area they experience a pain in their knee and their heart.

The Lepcha name for this caterpillar is called 'Pachek - bu'.
Pachek means an individual who wanders and eats.
It also means 'Almost' for example if you use it in a sentence - I almost got killed!!

Apparently Pachek-bu used to be eaten by hunters strolling by, whenever anyone comes by they start waggin their lower part of the body vigorously.
Legend says that they made negotiations with the hunters that whenever they moved their body like that they spoke to the hunters convincing them that they should leave them this time and should come tomorrow when they would be fatter and juicier as they are voracious eaters, only for the hunters to realize that they were fooled as they would never be seen in the same spot twice.
