Insect TAXONOMIC DIVERSITY
By: Tyler AndersonSlide2
Insect order list:
Ephemeroptera
Odonata Coleoptera
Blattaria
Isoptera
Dermatptera
Orthoptera
Phasmida
Hemiptera
Lepidoptera
Diptera
Siphonoptera
Hymenoptera
Mantodea
PlecopteraSlide3
Ephemeroptera:
Mayflies are aquatic but similar body shape to the adults, they have gills along the sides of their abdomen which look similar to fine
leaves
Mayflies
.Slide4
Odonata:
Dragonfly’s characteristically have large rounded heads covered mostly by well-developed,
compound
eyes, two
pairs of long, transparent wings that move independently, and elongated
abdomens
Dragonflies and DamselfliesSlide5
Blattaria:
eggs usually contained in ootheca
leathery forewings.
male genitalia asymmetrical
cerci variable, with one or more
segments
RoachesSlide6
Isoptera:
•Pale, elongate body
•2 pairs of membranous wings of equal length. Wings are present in reproductive castes only and shed after mating
•Mandibulate (chewing)
mouthparts
Termites
/ White Ants
Slide7
Dermatptera:
Earwigs have slender flattened body, bead-like antennae, and are easily recognized by the pair of large pincers (cerci) at the tip of the
abdomen
EarwigsSlide8
Orthoptera:
large descending lateral lobes,
nymphalid
wing rudiments reversing their orientation in later instars and hind tibiae with two dorsal teeth
rows
Grasshoppers
/ Locusts / Crickets / KatydidsSlide9
Phasmida:
Stick and Leaf-insects as their name implies are a medium sized order of insects most of which look like sticks or leavesSlide10
Hemiptera:
• 2 pairs of wings, although some species may be wingless and others have only forewings. Wings are generally membranous but in some species the forewings may be hardened at the base
• Piercing or sucking mouthparts appearing as a sharply pointed tube known as a proboscis or rostrum, which extends from the underside of the head
•Compound eyes of various forms
• Up to 3 ocelli presentSlide11
Coleoptera:
hind wings folded under elytra, with reduced venation
hind two thoracic segments (mesothorax+metathorax=
pterothorax
) broadly connected with abdomen, so that the primary functional units of body are head /
prothorax
/ pterothorax + abdomen, rather than the more typical head / thorax / abdomen of many other insects. genitalia retracted into abdomen Beetles
/ WeevilsSlide12
Lepidoptera:
Mouthparts form a coiled tube (proboscis) beneath the head
Antennal type:
Butterflies: knobbed or hooked at tip
Moths: thread-like, spindle-shaped, or comb-like
Front wings large, triangular; hind wings large, fan-shaped
Body and wings covered with small, overlapping scalesButterflies / MothsSlide13
Diptera:
Antennae
filiform, stylate, or aristate
Mouthparts suctorial (haustellate)
Mesothorax larger than pro- or metathorax
One pair of wings (front); hind wings reduced (halteres)
Tarsi 5-segmented True Flies / Mosquitoes / Gnats / MidgesSlide14
Siphonoptera:
Body bilaterally flattened
Mouthparts suctorial (haustellate)
Large bristles (ctenidia) often present on head or thorax (
genal
and pronotal combs)Hind femur enlarged, adapted for jumping
FleasSlide15
Hymenoptera:
Compound
eyes well developed.
Tarsi usually 5-segmented.
Triangular stigma in front wings.
Hind wings smaller than front wings, linked together by small hooks (hamuli).
Narrow junction (wasp waist) between thorax and abdomen - except in sawflies and horntails.Ants / Wasps / Bees / Sawflies / HorntailsSlide16
Mantodea:
Filiform antennae
Head triangular with well-developed compound eyes
Mouthparts mandibulate, hypognathous
Prothorax elongate with large, spiny front legs adapted for catching prey
Front wings thickened, more slender than hind wings
Mantids / Praying MantidsSlide17
Plecoptera:
Antennae
long, filiform
Front wings long and narrow; M-Cu crossveins form distinctive boxes near center of front wing
Hind wings shorter than front wings; basal area of hind wing enlarged and pleated
Cerci long, multi-segmented
StonefliesSlide18
