It's tough, energy efficient and should last a lifetime with minimal upkeep. ICF Insulated Concrete Forms are premade forms that fit together like legos or large interlocking blocks. The outside of the form is flat sheets of foam insulation. These sheets are connected with plastic framework.

The ancestors of present-day insects were probably worm-like arthropods with a simple mouth opening near the front of a bilaterally symmetrical body. Over many eons of time, tissues and appendages near the mouth opening came to be adapted for gathering and manipulating bits of solid food. As insects evolved, they became more complex, expanded in range, and adapted to new food resources. The structure and function of their mouthparts changed right along with their evolving diet and life style. Examples of adaptive radiation can be found just about everywhere in the insect world think about variability in legs, wings, and antennae, for example. Entomologists pay close attention to mouthparts because their structure allows us to infer what type of food is consumed — plant or animal, solid or liquid, dead or alive. There are five basic components that form these mouthparts:.
