FLAGGED

How do Orthopterans generally eat and how are their mouthparts modified for feeding?

Chewing mouth parts

1. 3 regions on body (head, thorax, abdomen)

2. Thorax has 3 segments with 1 pair of legs/segment

3. 2 pairs of wings (lost or reduced in some species)

4. Development varies from no metamorphosis to complete metamorphosis.

3 regions of insect body.

Where are the wings and legs located?

3 regions: head, thorax, abdomen

Wings and legs on thorax.

Phylum: Arthropoda

Subphylum: Uniramia

Class: Insecta

Order: Odonata (characterized by teeth)

Dragonfly

Other common species: damselflies

What do members of Odonata eat?

Are they considered beneficial to humans?

Eat other aquatic and flying insects

Very valuable for pest control.

At rest, dragonfly wings are splayed horizontally.

Damselfly wings rest vertically.

How to recognize true bugs

What type of mouthparts?

When wings are at rest, hemipterans have a distinctive X shape on their back.

Homopterans have distinctive midline line between wings.

Piercing and sucking mouthparts.

What type of metamorphosis characterizes Coleoptera?

Are some species employed as biological control agents?

Are some considered pests?

Do complete metamorphosis (larvae to pupae to adult)

Ladybird beetles and other used to control other insect populations

Corn root worms, click beetles, weevils, etc are pests.
