The typical functions of the three main parts of the insect:
- Head - sensory organs, brain, mouth parts
- Thorax: muscles for legs and wings
- Abdomen: the systems - digestion, respiration, excretion, and reproduction.
Drawing an Insect
A bug drawing will contain the three basic parts.
Add eyes, antenna, and mouthparts to the head.
Add six legs and wings, if applicable, to the thorax.
The abdomen is sometimes just an oval without discernable details,
however; when drawing an insect from life, you might observe one or more
of these abdomen features: a stinger, spiracles (the holes for the
breathing tubes), segments, a hook on the end, stripes, etc.
