Baguroms (バグロム) are insect like creatures, and there are many types.

They are all under the control of Diiva, and only the queen is in the form of a human.

Jinnai had the ability to talk to the Bagurom, and gave them some names: Katsuo, Namihei, Masuo, Tara-chan, Ikura-chan, Wakame.
(Yes, those are the names of the characters in Sazae-san too.)
