Konbu
Kombu, Konbu Seaweed, Kombu Seaweed
noun
Insect cloth is actually konbu. Konbu seaweed is very common in Japan, and it's delicious. And insects happen to love using it as cloth, too. They make all their clothes out of konbu.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. The 布 part gets changed to ぶ, probably because if a food doesn't have konbu you say boo (ぶ).
