1. Insect taxonomic diversity
By: Michael Brown

2. Insect orders Ephemeroptera Odonata Blattaria Isoptera Dermatptera
Orthoptera
Phasmida
Hemiptera
Coleoptera
Lepidoptera
Diptera
Siphonoptera
Hymenoptera
Mantodea
Plecoptea

3. Ephemeroptera In complete egg development (egg, nymph, adult)
Immatures are aquatic (naiads)
Unable to fold wings back
Common in freshwater habitats worldwide

4. odonata
While both dragonflies and damselflies belong to the Odonata and share many common features, then are a number of noticeable differences as well. Even before hatching from the egg, differences in morphology of the egg distinguish dragonflies (Anisoptera) from damselflies (Zygoptera).

5. blatteria
Cockroaches leave chemical trails in their feces, as well as emitting airborne pheromones for swarming and mating

6. isoptera Hemimetabola Orthopteroid
incomplete development (egg, nymph, adult)
Orthopteroid
closely related to Blattodea and Mantodea
Distribution: Extremely common in tropical and subtropical climates.  Generally less abundant in temperate regions.

7. DErmatptera Hemimetabola Orthopteroid
incomplete development (egg, nymph, adult)
Orthopteroid
closely related to Orthoptera and Phasmatodea
Distribution: Common and widely distributed throughout the world.  Largest diversity is found in the tropics and subtropics

8. orthoptera Filiform antennae Hind legs modified for jumping
Front wings thickened and parallel- sided (tegmina

9. phasmida Hemimetabola Orthopteroid
incomplete development (egg, nymph, adult)
Orthopteroid
closely related to Orthoptera and Dermaptera
Distribution:  Common in tropical and subtropical climates where they are found living on their host plants.

10. hemiptera Hemimetabola Hemipteroid
incomplete development (egg, nymph, adult)
Hemipteroid
closely related to Thysanoptera and Psocoptera
Distribution: Abundant worldwide.  All species are terrestrial herbivores.

11. coleoptera
These beetles are the heaviest of all insects, yet they are strong fliers that buzz loudly when visiting flowers for nectar and pollen.   The larvae live in the soil where they feed on roots.

12. lepidoptera Front and hind wings with large surface area
Body and wings mostly covered with tiny pigmented scales

13. diptera Only one pair of membranous wings present
Hind wings modified as halteres

14. siphonoptera Teardrop-shaped body bilaterally flattened
Long hind legs adapted for jumping
Heavy bristles (ctenidia) often present on gena and/or pronotum

15. hymenoptera Holometabola
complete development (egg, larva, pupa, adult)
The Hymenoptera is divided into two suborders:
Symphyta (sawflies and horntails) have a broad junction between thorax and abdomen
Apocrita (ants, bees, and wasps) have a narrow junction between the thorax and abdomen.
Distribution: Common worldwide. Third largest order of insects

16. mantodea Hemimetabola Orthopteroid
incomplete development (egg, nymph, adult)
Orthopteroid
closely related to Orthoptera and Blattodea
Distribution: Common in tropical and subtropical climates.

17. plecoptera Hemimetabola Orthopteroid
incomplete development (egg, nymph, adult)
Orthopteroid
closely related to Orthoptera and Embioptera
Distribution: Common in and around fast-moving streams in temperate and boreal climates.
