I agree nightshade. I've got quite a few insect books, that for some reason, the author feels are most useful if the image is printed actual size
Lots of blank space on every page and the odd spec of a drawing with a 30 word description - useless. Only an idiot would buy them...DOH!
I'll add to the list when I've dug them all out to check the author's name etc, but there aren't many that I'll be able to recommend.
