Several days ago, I found "Ashinaga-bachi no su"（アシナガバチの巣）, paper wasp's nest in my house's garden when I got rid of weeds. It had very good size, so I took this photo.
Paper wasp is said a kind of "Eki-chu"（益虫） in Japan because it catches caterpillars in fields to eat them. In this case, "Eki" means "beneficial" and "chu" means "insect".
P.S. I have learned this word "paper wasp" just when I would write this article. But, in this case, I think that the Japanese word "Ashinaga-bachi" gets its feature better than the English.
