We are using Apolgia's Flying Creatures of the Fifth Day book this year. Since the book suggests studying the insects when they are easily accessible, we have jumped forward to Chapter 9. I found a wonderful resource to supplement our studies from of all places.....the Orkin Man. I quess it makes sense to study the enemy you're trying to kill. Anyway, you can find coloring pages, insect games, and lesson plans at their learning center.
Now I'm gathering materials for Feeding Frenzy--a lab to discover the different types of insect mouthes: piercing, sponging, chewing, sucking, and cutting.
