1. Orders
Thysanoptera
Siphonaptera
Neuroptera

2. "thysanos” = fringe + "ptera" = wings
THYSANOPTERA
"thysanos” = fringe + "ptera" = wings
“Thrips”

3. Rasping-sucking mouthparts
THYSANOPTERA
Very small
Antennae short
Rasping-sucking mouthparts
Front and hind wings with a dense fringe of long hairs (many wingless species)

4. THYSANOPTERA
Metamorphosis
Paurometabolous
(gradual)
egg, nymph, adult

5. THYSANOPTERA
Economic Importance
Many thrips are pests of plants, especially grain crops, fruits and vegetables, and ornamentals
They can transmit plant pathogens
Predatory thrips are beneficial

6. Lacewings, Antlions, Dobsonflies
Order NEUROPTERA
Lacewings, Antlions, Dobsonflies

7. Metamorphosis
Holometabolous
(complete)
(egg, larva, pupa, adult)

8. Green Lacewing Most adults are green Chewing mouthparts
Golden or copper-colored eyes
Front and hind wings similar in shape and size
Long threadlike antennae

9. Neuroptera Terrestrial: important predators
- lacewings: aphids, scale insects, thrips
- antlions: larvae build pits for ants
Aquatic: dobsonflies
- feed on aquatic insects
- serve as food for fish

10. Siphonaptera

11. “a” = without + “ptera” = wings
Siphonaptera
“a” = without + “ptera” = wings
Fleas
Body bilaterally
flattened
2. Piercing/sucking
mouthparts
3. Hind coxae enlarged
for jumping

12. Egg  Larva  Pupa  Adult
Metamorphosis
Holometabolous
Egg  Larva  Pupa  Adult

13. Where do siphonapterans live? - larvae live off host
- adults live on host
What do siphonatperans eat?
- larvae are scavengers
- adults eat blood

14. Economic Importance - Irritating bites - Transmit disease
- BUBONIC plague and the rat flea
