Document Summary

One ancestral insect to all forms that come up on land. 3 tagma (body parts: head: specialized for sensory input and feeding, thorax: locomotion and movement. A block of muscle to work the 3 walking legs: abdomen: all the functions of life occur. Extended and contracted like an accordion: they all have the same morphological tagma. The way the light is refracted, the picture is just a huge blur together. 3 types of cones except it does not see red, it sees uv. Flight and wing folding mechanism: allowed insects to crawl around, burrow and stuff. Flight allowed insects to disperse and move around: may be able to fly into areas where plants are seasonal. Cuticle is in two parts: procuticle, epicuticle: glands ooze material along the surface to waterproof the insect. Use a spermatophore: puts it into a waterproof container. Females put a shell on her egg, therefore it is waterproof.
