多分スカシバの幼虫。
上田のほうではこれで
大分パープルもやられたらしい。

木屑様の塊が枝についていて、
それを取り払うと新梢に
穴が開いている。

穴より基側を切り開くと、
もぬけの殻。

反対側（先端の方）を見ると
穴から頭が覗いている。

中にはやっぱりいましたね～。
こんな格好して驚くほど動きは
すばやい。見つけ次第捕殺。

A kind of moth which sometimes
mada a huge damage to grapes.
Young Nagano Purple vines in Ueda
area seemed to have been damaged
by this kind of pest.

When you find a sawdust like
clod, remove it and you will find
a hole on the new shoot.

I found one and cut the　base
side of the shoot around the hole. There was
nothing.

Then looked at the other side of
the shoot, then I saw the head of
the larva.

Inside the hole, there was one.
It moves very quickly and you should be
careful not to lose it. Whenever you find
one, you have to smash it.
