Orthoptera
What metamorphosis does the Order Orthoptera go through?
Paurometabolis
Describe Ametabolous:

Describe Hemimetabolous:
- “incomplete” metamorphosis
- Nymphs are aquatic and have gills
- Very different from adults
Describe Paurametabolous:
- “Gradual” metamorphosis
- Nymphs and adults live in same habitat
- Changes include size, body proportions, Oecelli, andother structures
descrine Holometabolous:
- Complete Metamorphosis
- Egg - Larvae - Pupae - Adult
- Each stage has a different form
- Larvae and adults often in different habitats and have different purpose
Describe the mouthparts of Orthoptera insects?
Chewing mouthparts
What are some spot ID characteristics of Othoptera?
- Filiform antennae.
- Hind legs modified for jumping.
- Front wings thickened and parallel-sided (tegmina).

Front wings are thickened and paralell sided
Front wings are thickened and paralell sided….this is called ________.
Tegmina

Order Hemiptera go through what kind of metamorphosis?
Paurometabolous
What are the spot ID characteristics of Heteroptera?
- Mouthparts form tubular proboscis at front of head.
- Front wings cross over to form “X” pattern on back.
- Triangular scutellum in center of back.
- Front wings leathery at base and membranous toward apex – called hemelytra
