Eretmocerus eremicus is a tiny parasitic wasp (~1 mm in length) that is indigenous to the southern deserts of California and Arizona and is an important parasitoid of whiteflies in these areas. Females of this beneficial insect are a pale lemon color with green eyes and clubbed antennae. The name Eretmocerus is Latin for 'club shaped' referring to the antennae. Males are yellowish brown in color. Besides killing whitefly from parasitism, the female adults also host feed, killing more whitefly nymphs. Eretmocerus eggs hatch after 4 days, the larvae develop for around 12 days and the adults live for another 6-12 days, depending on temperature and availability of food.
