|
|
Dermaptera
|
(earwigs)
* heavily sclerotized, posterior forceps at tip of abdomen |
|
|
Phasmatodea
|
(walking sticks)
* adults medium-sized to large insects that are often elongate and cylindrical; some dorsoventrally flattened |
|
|
Embioptera
|
(web spinners)
* spin silk from swollen glands on basal segment of each fore tarsus |
|
|
Psocodea
|
(parasitic) (chewing & sucking lice - “Phthiraptera”)
* dorsoventrally flattened, apteryous ectoparasites |
|
|
Psocodea B
|
(parasitic) (bark and book lice - “Psocoptera”)
* asymmetrical chewing mandibles |
|
|
Thysanoptera
|
(thrips)
* 3-part needle-like mouthparts composed of paired maxillary stylets and the left portion of the mandible |
|
|
Hemiptera
|
(true bugs, cicadas, leafhoppers, planthoppers, treehoppers, aphids, scales, mealybugs, spittlebugs)
* rostrum (or proboscis): (1) mandibles and maxillae form a needle-like stylet & (2) grooved, beak-like labium that supports stylet |
|
|
Neuroptera
|
(lacewings, ant lions, owlflies)
* two equal-sized, intricately-veined wings |
|
|
Raphidioptera
|
(snakeflies)
* Elongate prothorax AND two equal-sized, intricately-veined wings |
|
|
Coleoptera
|
(beetles)
* adults have elytra: sclerotized and rigid forewings that cover pleated hindwings (used in flight) and often the abdomen as well |
|
|
Diptera
|
(flies)
* halteres: hindwings modified into club-like knobs; stabilize flight |
|
|
Siphonaptera
|
(fleas)
* laterally compressed, apteryous ectoparasites |
|
|
Trichoptera
|
(caddisflies)
*adults moth-like; wings covered with setae (hair-like cuticular extensions) |
|
|
Lepidoptera
|
(butterflies & moths)
* wings covered with scales (modified setae); scales responsible for wing color and pattern * distinctive coiled proboscis allows adults to suck liquids (often plant nectar) |
|
|
Hymenoptera
|
(sawflies, wasps, ants, and bees)
* ants, bees and wasps with the 1st abdominal segment (propodeum) fused with the thorax (the whole unit = mesosoma); the 2nd (and sometimes 3rd) abdominal segment greatly constricted (petiole) |
|
|
Archaeognatha
|
(bristletails, rockhoppers)
* monocondylous: mandibles articulate in one place with jaw. Less stable and weaker than dicondylous jaws (all other orders) |
|
|
Zygentoma
|
(silverfish)
* aptyerygote AND dicondylous |
|
|
Ephemeroptera
|
(mayflies)
* subimago: penultimate instar winged |
|
|
Odonata
|
(dragonflies & damselflies)
*males have secondary copulatory apparatus on ventral base of abdomen; pairs form tandem wheel during copulation. |
|
|
Mantodea
|
(mantids)
* raptorial forelegs: tibia & femur with interlocking spines |
|
|
Blattodea
|
(roaches - Blattoidae)
* 1st segment of thorax shield-like and extended over head |
|
|
Blattodea B
|
(termites - Termitoidae)
* guts contain endosymbiotic bacteria (or protists) that aid in the digestion of cellulose; individuals exchange food and symbionts |
