Red insects only bite barbarians. If a red insect bites you then you have barbarian blood! Waaay back a barbarian was your aunt or uncle or great great grand pappy! But the insects kinda hurt, so it's a bit of a downside I guess.

Following the insect, it leads you to a red insect demonstration, all shouting: "Ban (ばん) the barbarians! Ban the barbarians!".
