1 Developing Entomological Skills and Techniques (how to be a bugdork)

2 Why Insects? Most numerous and diverse animals Live in all habitats Most important (good and bad) for humans They rock and it’s fun…

3 Kingdom ANIMAL Phylum ARTHROPODA

4 Orders Collembola Thysanura Ephemeroptera Odanata Phasmatodea Orthoptera Mantodea Blattodea Isoptera Dermaptera Plecoptera Psocoptera Phthiraptera Hemiptera Thysanoptera Neuroptera Coleoptera Mecoptera Siphonaptera Diptera Trichoptera Lepidoptera Hymenoptera

5 Orders Collembola Thysanura Ephemeroptera Odanata Phasmatodea Orthoptera Mantodea Blattodea Isoptera Dermaptera Plecoptera Psocoptera Phthiraptera Hemiptera Thysanoptera Neuroptera Coleoptera Mecoptera Siphonaptera Diptera Trichoptera Lepidoptera Hymenoptera NON-Insects

6 Types of Metamorphosis Ametabolous (most primitive) Hemimetabolous Paurometabolous Holometabolous (most advanced)

7 Ametabolous – no metamorphosis Insect Metamorphosis Young = nymphs

8 Ametabolous – no metamorphosis Insect Metamorphosis * The stages of immature insects are called instars

9 Hemimetabolous – incomplete metamorphosis Insect Metamorphosis

10 Hemimetabolous – incomplete metamorphosis Insect Metamorphosis Naiad – aquatic nymph

11 Paurametabolous – gradual metamorphosis Insect Metamorphosis instars

12 Paurametabolous – gradual metamorphosis Insect Metamorphosis “Nymph” 1 2 3

13 Holometabolous – complete metamorphosis Insect Metamorphosis Adults and young look completely different instars 123

14 - maggot, worm-like shaped body - feeding apparatus either mouth hooks or mandibles - no legs Vermiform: e.g., flies Insect Metamorphosis

15 - Slightly flattened body - mandibulate feeding apparatus - 3 pairs of thoracic legs Elaterifom: e.g., mealworms Insect Metamorphosis

16 - caterpillar-like shaped body - mandibulate feeding apparatus - 3 pairs of thoracic legs and 5-7 pairs of abdominal prolegs Eruciform: e.g., butterflies Insect Metamorphosis

17 Fall Armyworm

18 Important Questions Wings or no wings? – How many? Kind of Mouthparts? Where did I find it? Any special adaptations? – Raptorial legs, swimming legs – Camouflage?

19 Order Collembola: Springtails Coll = glue Embola= a bolt or wedge (collophore)

20 Springtails: Order Collembola

21 Order Thysanura: Silverfish Thysano= fringed ura= tail

22

23 Order Ephemeroptera: Mayflies ephemeros= short lived

24 Order Ephemeroptera: Mayflies

25 Order Odonata: Dragonfly and Damselfly dragonflies keep wings out when at rest… …while damselflies keep wings back over body at rest

26 Odonata = toothed jaw Order Odonata: Dragonfly and Damselfly

27 Order Phasmatodea: Walking sticks and Leaf Insects Phasm = phantom

28 Order Orthoptera: Grasshoppers, Crickets, Locusts & Katydids Ortho= straight Ptera= winged

29

30 Order Mantodea Praying mantids, soothsayers

31

32 Order Blattodea: Roaches Blatta - Greek word for roach

33

34 Order Isoptera: Termites Iso = even ptera = wing

35 Order Dermaptera: Earwigs Derm = leather Ptera = wing

36 Order Plecoptera: Stoneflies Pleco = folded or pleated Ptera = wing

37

38 Psoco= gnawing Ptera= wing Bad Name! Think of them as winged insects that gnaw. Order Psocoptera: Bark & Book lice

39

40 pthir = lice aptera = no wings Two Suborders – Mallophaga: The chewing lice – Anoplura: The sucking lice Order Pthiraptera: Lice

41 Suborder Mallophaga

42 Mallophaga

43 Anoplura: Sucking Lice

44 Order Hemiptera: True Bugs, Scales, Aphids, Hoppers Etymology: hemi = half ptera = winged Hemiptera: Order Name Suborder Heteroptera = true bugs Suborder Auchenorrhyncha = hoppers and cicadas Suborder Sternorrhyncha = aphids and allies Refers to the true bugs

45 Suborder Heteroptera Hemelytra - sclerotized basal portion of wings

46

47 Aphids

48 leafhoppertreehopper planthopper

49 Order Thysanoptera: Thrips Thysan= fringed Ptera= winged

50 Thysanoptera

51 Order Neuroptera Neuro = nerve Ptera = wing Tons of different insects lumped into this group…

52 Lacewings

53 Dobsonflies

54 Antlions

55 Owlflies

56 Mantisfly

57 Order Coleoptera: Beetles

58 Coleoptera koleos- sheath (from Aristotle) fore wings called elytra Serve to protect the membranous hind wings (used in flight)

59 Beetle diversity

60 Order Mecoptera: Scorpionflies

61 Order Siphonaptera: The Fleas Siphon: a tube Aptera: wingless

62 Order Diptera: True Flies Di= two Ptera= wings True flies have only one pair of wings The hind pair = flight stabilizers called halteres.

63

64 Order Trichoptera: Caddisflies Tricho= hair Ptera= wings

65 Caddisfly larvae

66 Order Lepidoptera: Butterflies & Moths

67 Lepid = scales Ptera = wings

68

69 Order Hymenoptera: Bees, Wasps and Ants

70 Hymenoptera (Bees, wasps, ants) hymen = membrane Ptera = wings Greek Goddess of Marriage: Hymeno Goddess of marriage – Named for the joining of the wings

71 Hamuli = Small row of hooks on hind wing

72 Tricksters: Assassin Bugs and Ambush Bugs Count the Beak Segments! 3 4 Does the beak fit into a groove???

73 Tricksters: Flesh Flies and House Flies Flesh FlyHouse Fly

74 Horn fly Stable fly

75 Class Arachnida Order Solifugae Camel Spiders!!!!!
