According to Yemenite tradition, the edible locust referred to in the Torah is identified by the figure resembling the Hebrew letter "chet" (ח) on the underside of the thorax. The most common of these in Yemen was the desert locust ("Schistocerca gregaria"), whose color ranges from yellowish-green to grey, to reddish in colour when it reaches maturity (, , or ). In Yemen, the locust and the grasshopper share the same Arabic name, although Jews in Yemen recognize the differences between the two.
