Taeniopoda eques, the western horse lubber grasshopper, is a relatively large grasshopper species of the family Romaleidae found in the arid lower Sonoran life zone of the southwestern United States and northern Mexico.
Northern populations are identifiable by their shiny black bodies and black and yellow reticulated forewings.
Some southern populations are yellow in the adult stage.
The species is unique in using its black coloration to thermoregulate and in being chemically defended.
The aposematic coloration warns vertebrate predators of its unpalatability and allows the grasshopper to roost conspicuously upon desert shrubs.
