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
