Cibolacris and Xeracris occur on bare open ground, primarily on sand or gravel areas in arid regions. They look and behave much like Bandwing Grasshoppers (subfamily Oedipodinae) and are easily confused with them. However, these small grasshoppers with transparent wings are more inconspicuous than most Bandwing species, and are easily overlooked.
Ligurotettix is quite different in behavior from the other two genera, sitting on branches inside of desert shrubs where the males stridulate loudly. They are very hard to see, moving quickly around to the far side of branches when disturbed, though if disturbed enough will as often drop to the ground or fly to another bush.
These are relatively slender to average built grasshoppers that resemble Band-winged Grasshoppers (Oedipodinae), but have transparent (yellowish to bluish) wings. They have rounded heads with relatively vertical faces and relatively large eyes. They are all rather plain and dull grayish or brownish in coloration, often with dark speckling and/or small dark spots.
Perhaps they are related to the Aulocara group, but this is uncertain. The insects included here are more slender, fly longer distances, and seem more alert than most members of the Aulocara group. There is also a strong similarity of Cibolacris and Xeracris to the Old World genus Hyalorrhipis (typically placed in the subfamily Oedipodinae), and there is some molecular evidence suggesting a kinship between Cibolacris and Hyalorrhipis, however this needs further investigation.
Ligurotettix is a very distinctive genus, probably not closely related to the other two at all, but it has been associated with them in recent years. It is left with them here, primarily because it doesn't fit anywhere else.
