Insect Body Plan

Insect Body Plan four wings six legs modifications none halteres

Insect Body Plan compound eyes antennae

insect body divided into 20 segments Insect Body Plan grouped into three tagma insect body divided into 20 segments

each tagma has its own job Insect Body Plan each tagma has its own job head

Insect Body Plan thorax abdomen

mouthparts adapted for chewing Insect Body Plan sucking mouthparts adapted for chewing or other

Insect Body Plan Open circulatory system – blood flows in a hemocoel, not in blood vessels Simple respiratory system – made of a system of tracheal tubes and spiracles (openings on abdomen)

Insect Life
