8

• You are responsible for 4 families
• Libellulidae
• Aeshnidae
• Gomphidae
• Corduliidae

Its all about the wing veins (sorry)
Brace vein
Nodus
Dark spot stigma
In red are the Triangles

11
F Aeshnidae

• Darners

12
Aeshnid wings
13
F Gomphidae

• Clubtails
• Compound eyes DO NOT meet on the top of the head
• Terminal abdominal segments often enlarged (thus
  the name)
• Wings have a brace vein and prominent triangles

14
Gomphid wings
15
F Libellulidae

• Common Skimmers
• Hind margin of compound eye straight
• Inner margin of hind wing rounded
• Wings lack a brace vein, anal loop looks like a
  foot

16
Libellulid Wings
17
F Corduliidae

• Green-eyed skimmers
• Hind margin of eyes slightly rounded
• Wings lack brace vein, have anal loop that is
  less like a foot.

18
Corduliid wings
19
O Odonata sO Zygoptera

• You are responsible for 3 families
• F Lestidae
• F Coenagrionidae
• F Calopterygidae

20
Damselfly wings (Lestids and Coenagrionids)
Stalked
Antenodal Crossveins
21
F Lestidae

• Spread-wing damselflies
• Wings are held spread at rest
• Wings stalked
• Two ante-nodal crossveins, M3 arises near arculus

22
F Coenagrionidae

• Narrow-wing damselflies
• Hold wings back at rest
• M3 vein arises behind nodus
• 2 ante-nodal cross veins
• Wings stalked, very narrow- less venation than
  Lestids

23
F Calopterygidae

• Broad-winged damselfly
• Wings NOT stalked, gradually narrow
• 10 or so antenodal crossveins
• More highly venated than other families
• Often have colored patches on wings, hold wings
  together at rest

24

• F Tettigoniidae

26
F Acrididae

• Grasshoppers
• Antennae shorter than body
• Well-developed wings, mandibles
• Can be colorful, usually relatively cryptic
• Tympanum on first abdominal segment
• 3 tarsal segments

27

28

• Blaberidae- All TX Species are GREEN
• Blatellidae- German cockroach, smaller than
  blattidae and often with stripes on pronotum

  wings, females wingless
• Look in collection to see how they are different

33
O Isoptera
