About Chrysina woodi (Horn, 1884)
Chrysina woodi, commonly called Wood's jewel scarab, is a species of shining leaf chafer belonging to the scarab beetle family Scarabaeidae. This bright green beetle is native to Chihuahua, Mexico, and the U.S. states of New Mexico and Texas. It measures 25–35 mm (1.0–1.4 inches) in length and resembles the related species Chrysina beyeri. The two can be distinguished by leg coloration: in C. beyeri, all legs and tarsi are blue-purple, while in C. woodi, the legs are green and only the tarsi are blue. The species name was first published as woodi in meeting minutes in 1884, before a formal description published in 1885 that used the spelling woodii. Under Article 50.2 of the International Code of Zoological Nomenclature, the 1884 name and original spelling takes precedence. Documented adult diets of this species consist mostly of Texas black walnut (Juglans microcarpa), though adults have also been reported feeding on a few other plant species.
