| What are the main features of Exopterygota? | -Immature = adult in aspect and habits -Nymph have wing primordia that develop externally -Simple incomplete metamorphosis (heterometabolous) |
| Which major orders belong to Exopterygota? |
-Orthoptera
-Psocoptera
-Hemiptera
-Thysanoptera

Lepidoptera |
| Characteristics of Lepidoptera | -Adult: body & wings covered with scales or hairs. Mouthparts = proboscis (feed on nectar or don't feed at all) -Larva: Eruciform (caterpillar like) , chewing mouthparts (phytophagous) |
| Characteristics of Diptera |
-Mesothoracic wings = halteres for balance
-Saprophytic adults
-Apodous larva feed on soft tissue

| Characteristics of Hymenoptera | -Mouthparts: jaws for chewing and modified lip adapted to suck. -Narrowing between the 1st and 2nd abdominal segment. -Types of larvae: eruciforms (phytophagous) and apodous (parasitoids) -No sex :( arrhenotoky parthenogenesis |
| Characteristics of Coleoptera | - Chewing mouthparts both in larval and adult stage - Elytra: sclerotized mesothoracic wings - Most species are herbivores but there are also many predators. |
| Characteristics of Neuroptera | - Predatory (both adult and larvae) - Campodeiform larvae, chewing or sucking mouthparts. They feed on small arthropods, aphids, coccids and mites. -Important families: Chrysopidae, Hemerobiidae & Coniopterygidae. |
