Based on their feeding behaviors, three major types of insect herbivores can be distinguished, which evades the constitutive defense;

A) Phloem feeders                                                                    i) caterpillars, grasshoppers, and beetles

B) Cell-content feeders                                                            ii) aphids and whiteflies

C) Chewing insects                                                                    iii) mites and thrips
