I thoroughly enjoyed the article, but have to write the author up on his views on terrestrial pattern use in the UK... they simply aren't true (I live in north west England). Anglers here use many different terrestrial patterns, in fact I think you'd struggle to find a box without at least a beetle imitation in it.

It is true we don't use much in the way of grasshopper patterns and the like - but for good reason, they are relatively few and do not end up in rivers all that frequently. Many of the north-country spider imitations could be argued to represent terrestrials, a few are tied directly to imitate them. A lot of anglers use ant patterns, though I've always found them more useful on wind-swept lakes than rivers, but thats just my experience.

Interesting article, just not sure about the Uk bashing

All the best, Steve J.
