My favorite thing about the lack of graphics is the creativity of it. There's no 'this is what your insect looks like' which allows creative freedom with what you think the insects look like. Using the brief descriptions, it's fun to decide for yourself the insects' proportions, color, and shape! I know if there are graphics added, I'll probably keep them off.
