Description
The dimensions of the Texas Emerald, (Somatochlora margarita) are 50-54 mm in length; 32-41 mm abdomen length; and the hindwing length: 32-37 mm.[2]

Range
Somatochlora margarita is native to the two U.S. states of Texas and Louisiana. It is known to inhabit just twelve combined eastern Texas counties and western and central Louisiana parishes. The current known range is northwest of Houston and extends east into central Louisiana, reaching as far as Alexandria. The Texas emerald is rarely seen by humans because of its tendency of flying up and perching in and or on the canopy in trees or forests.[3]
