Sketch of a dragonfly body

showing the body parts...pg. 10

by Barbara Chasteen

DRAGONFLIES - Anisoptera:


Large, heavy-bodied; ordinarily larger than damselflies.

Wings are held open & flat or down & forward when perched.

Large eyes are spaced very close together and in most families actually touch, creating a seam down the center.

Strong fliers; a few are even migratory.

Males have three terminal abdominal appendages and a bump (genitalia) under their second abdominal segment.

All females have only two terminal abdominal appendages and in many families they also have an ovipositor.

Most dragonflies lay their eggs directly into the water.

The southwest has at least 132 species in 45 genera representing all seven American dragonfly families:

1. Skimmers - Libellulidae (pages are below on this page)
2. Emeralds - Corduliidae (pages are below on this page)
3. Darners - Aeshnidae (pages are linked to from this page)
4. Clubtails - Gomphidae (pages are linked to from this page)
5. Spiketails - Cordulegasteridae (pages are linked to from this page)
6. River Cruisers - Macromiidae (pages are linked to from this page)
7. Petaltails - Petaluridae (pages are linked to from this page)
Southwestern distribution maps are up dated at least every January and based on information originally collected by Dennis Paulson (thru 2007). Odonata Central may have the most current information
