Lepidoptera (butterflies, moths)Greek “lepido”= scale, “ptero”= wing

Page 19: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Lepidoptera (butterflies, moths)Greek “lepido”= scale, “ptero”= wing

• Coiling-sucking mouthparts

Page 20: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Lepidoptera (butterflies, moths)Greek “lepido”= scale, “ptero”= wing

• Coiling-sucking mouthparts• Four wings covered with scales

Diptera (flies)Latin “di”= two, “ptero”= wing

Page 22: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Diptera (flies)Latin “di”= two, “ptero”= wing

Spot ID• Two wings

Page 23: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Diptera (flies)Latin “di”= two, “ptero”= wing

Spot ID• Two wings

– Hind wings reduced to halteres

Page 24: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Diptera (flies)Latin “di”= two, “ptero”= wing

Spot ID• Two wings

– Hind wings reduced to halteres

• Sponging-sucking mouthparts– Except mosquitoes

and some others that pierce skin

Diptera (flies)Latin “di”= two, “ptero”= wing

Page 26: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Hymenoptera (bees, wasps, ants)

Greek “hymen”=membrane, “ptero”=wing or

Hymen, the Greek god of marriage because the forewing & hindwings are joined

together with small hooks

Hooks not shown

Page 28: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Hymenoptera (bees, wasps, ants)Spot ID• Chewing mouthparts

Page 29: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Hymenoptera (bees, wasps, ants)Spot ID• Chewing mouthparts• Four membranous wings

Page 30: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

stinger at end of abdomen

Hemiptera (true bugs, also sometimes called Heteroptera)

Greek “hemisys” = half, “ptero” = wing

Page 33: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Hemiptera (true bugs)

Greek “hemisys” = half, “ptero” = wingSpot ID• A beak: piercing-sucking mouthparts

Page 34: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Hemiptera (true bugs)

Greek “hemisys” = half, “ptero” = wingSpot ID• A beak: piercing-sucking mouthparts• Forewings covering hindwings

– Wing half membrane, half thickened

Page 35: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Homoptera (hoppers, aphids, scales, cicadas)

Greek “homo” = uniform, “ptero” = wingSpot ID• A beak: piercing-sucking mouthparts• Forewings covering hindwings

– Wings all membranous

Page 36: Common Insect Orders Adapted from Berkeley Natural History Museums lesson “A Quick Way to Identify Common Insect Orders”

Homoptera (hoppers, aphids, scales, cicadas)

Greek “homo” = uniform, “ptero” = wingSome entomologists now combine Order

Homoptera with Order Hemiptera because the DNA has been found to be similar. In this case, Homoptera would be considered a suborder.

Neuroptera (ant lions, lacewings, mantidflies)

Greek "neuron" = nerve and "ptera" = wingsSpot ID• four membranous net-
