It's a good theory, Davies (and that's NOT sarcasm, I know it's hard to tell
sometimes) but it falls apart once you realize that Deva has been warring on
the Roshatrians, who are for all intents and purposes human, without ever
giving a smeg about having long involved social discourse with them. In fact,
I consider that one of the LARGER plot holes in El-Hazard; the fact that the
Bugrom, who have the intelligence of your average dog, managed to
differentiate between Jinnai and your average Roshtarian long enough to take
him to Deva. After all, they attack Makoto and Co. the instant they spot
them, and Jinnai wouldn't have had a Fujisawa-sensei tocome rescue him.

Isn't the simple answer that Jinnai's communication ability includes a 
charismatic quality vis-a-vis bugs?  What does the queen look like?
