PCA Exam: Insects, Mites, and Invertebrates
1. Chewing Mouth- includes the labrum, mandibles, hypopharynx, and the labrum-epipharynx
part
2. piercing-sucking insect mouthparts in which a syringe-like structure pierces plant cells and draws
mouthparts in its contents
3. Blood Feeding An elongated labium forms a protective sheath for the stylet that carries enzymes
Mouthparts that when the insect carries blood up it does not clot
4. rasping-sucking Scrape the surface of the leaf away and then feed on the sap using a cone shaped
mouthparts beak
5. Siphoning Feeding tube is uncoiled and extended to suck liquids into the mouth (butterfly)
mouthparts
6. Sponging The mandibles and maxillae are nonfunctional, and the remaining parts form a
mouthparts proboscis with a fan-shaped sponge at the tip, liquid food is mopped up by the
capillary action
7. Chewing-lap- Modified mouthparts that occur in bees. Includes a "tongue" that laps up liquids,
ping mouthparts as well as mandibles that can be used for various functions.

type mon in grasshopper or crickets
19. Hemelytra wing Front wings that are leathery or parchment-like at the base and membranous near
type the tip in some true bug species
20. Elytra wing type Hard, sclerotized front wings that serve as protective covers for membranous hind
wings, most common in beetle like species
21. Scales wing type Membranous wings that may be coated with scale to provide color, protection
from predators, and temperature regulation
