Big feller

These here cockroaches in this country can be intimidatingly big (this chap was over 10cm once I stretched his wee legs and horns), but seem a little more graceful, if that's the word than those I've seen in Europe and the Americas. For instance they don't instantly and guiltily scatter as soon as you turn on the light, but would rather hand around a while and stand their ground if necessary. They also seem solitary, which makes them appear less, well, grubby.
