Provisional Checklist of the Mecoptera (Scorpionflies) of Brackenridge Field Laboratory and Surrounding Areas
Prepared by R.W. Patrock (4 November 1988)

Fairly common, adults have been collected from the begining of September through December. Most often collected in heavy vegetation. Easily recognized because of the brownish-black patched wings. Larvae eat a variety of animal remains in the soil (Gassner 1963). 

Panorpidae (Common Scorpionflies)

Panorpa nuptialis Gerstaecker 1

Bittacidae (Hanging Scorpionflies)

Bittacus occidentis Walk. Texas1
