Classify the following (i.e. name the phylum, class, and order)

What are Blattodea and what are some distinguishing features?

Answer 24

Cockroaches

• Oval, flattened body
• Head is concealed beneath the pronotum (looks like a shield)
• Manibulate (chewing) mouthparts
• Antennae
• Wing development varies

Question 25

# Classify the following (i.e. name the phylum, class, and order) What are Phasmatodea and what are some distinguishing features?

Answer 25

Stick insects * **mimick sticks or leaves** * mandibulate mouthparts * all legs adapted for walking * vegetarian * some species are significant pests

Question 26

# Classify the following (i.e. name the phylum, class, and order) What are Orthoptera and what are some distinguishing features?

Answer 26

**Grasshoppers, crickets, katydids** * **hindlegs adapted for jumping** (i.e. they're big and muscley) * **filiform antennae (thin)** * short = locusts and grasshoppers * long = crickets and katydids * mandibulate mouthparts **locusts** * form swarms and marching/hopping bands (as nymphs) * once they're swarming, its too late for control due to their ability to migrate LONG distances very quickly * egg pods can reach densities of 500/m2 * moisture stimulates egg development * eggs laid in autumn enter diapause

Question 27

# Classify the following (i.e. name the phylum, class, and order) What are Odonata and what are some distinguishing features?

Answer 27

**Dragonflies** and **Damselflies** * **Two nearly-equal pairs of large membranous wings** * nymphs are aquatic * potential biological control for mosquito larvae

Question 28

# Classify the following (i.e. name the phylum, class, and order) What are the two Australian suborders of Odonata and how do you tell them apart?

Answer 28

**Anisoptera (dragonflies)** * wings usualy spread at rest **Zygoptera (damselflies)** * Wings usually held over the body at rest

Question 29

# Classify the following (i.e. name the phylum, class, and order) How would you tell the difference between a bug and a beetle?

Answer 29

Forewings * Coleoptera (beetles) have elytra (hardened forewings) that curve down and cover the body Mouthparts * Coleoptera have mandibulate mouthparts

Question 30

# Classify the following (i.e. name the phylum, class, and order) What are Dermaptera and what are some distinguishing features?

Answer 30

**Earwigs** * elongate body with **cerci modified into forceps** * incomplete metamorphosis * nocturnal * omnivorous * seedlings and flowers can be severely damaged

Question 31

# Classify the following (i.e. name the phylum, class, and order) What are Hemiptera and what are some distinguishing features?

Answer 31

**_Bugs_, aphids, scales, leafhoppers, cicadas** * **sucking mouthparts** * useful for distinguishing from beetles * usually have two pairs of wings with forewings hardened * can also have no wings * usually gradual/incomplete metamorphosis * many are pests * not only because they feed on plants, but because they're the main vectors of disease * some are predatory and very useful as biological control * e.g. mirid bugs

Question 32

# Classify the following (i.e. name the phylum, class, and order) What are Thysanoptera and what are some distinguishing features?

Answer 32

**Thrips** * piercing/sucking mouthparts * narrow wings with a fringe of setae (hairs) * diverse feed resources exploited * many induce galls * some are vectors of plant viruses

Question 33

# Classify the following (i.e. name the phylum, class, and order) What are Diptera and what are some distinguishing features?

Answer 33

**Flies, mosquitoes, gnats, midges** * **single pair of wings** * adult mouthparts = sucking, often adapted for piercing * complete metamorphosis * larvae don't have true legs

Question 34

# Classify the following (i.e. name the phylum, class, and order) What are Lepidoptera and what are some distinguishing features?

Answer 34

**Butterflies, moths** * **two pairs of membranous wings, _covered in scales_** * **mouthparts modified into a sucking proboscis** * larvae typically catarpillars with distinct head, thorax, and abdomen * prolegs on abdomen are not true legs (no segments)

Question 35

# Classify the following (i.e. name the phylum, class, and order) What are Neuroptera and what are some distinguishing features?

Answer 35

**Lacewings** * **two pairs of wings with numerous cross-veins** * mandibulate mouthparts * long, thread-like antennae * predatory * larvae control mites, aphids, thrips, etc.

Question 36

# Classify the following (i.e. name the phylum, class, and order) What are Coleoptera and what are some distinguishing features?

Answer 36

**Beetles** and weevils * **two pairs of wings** * **forewings** (mesothoratic wings) **hardened** (called **elytra**) * **mandibulate mouthparts** * complete metamorphosis * larvae with/without legs

Question 37

# Classify the following (i.e. name the phylum, class, and order) Describe the general characteristics of locust collective behavoir and outbreaks

Answer 37

* two phases regarding how they choose where to feed, solitarous and gregarious * gregarious = in groups * can be because they hatched together or because resources are limited * nymphs form hopper bands and basically walk along the ground * can be 50m to several km * band movement seems unpredictable * hypothesis is that it emerges from local interactions
