ground pearls - Margarodes spp. spp. (Insecta: Hemiptera: Margarodidae) spp., are primitive, subterrestrial relatives of the widely recognized, above ground armored scale insect (family Diaspididae). They are also sometimes referred to as earth pearls or pearl scale. While retaining well-developed fossorial legs with numerous setae (which scale insects do not have), ground pearls cannot secrete scales similar to their scale relatives (Beardsley and Gonzalez 1975). Instead, ground pearls excrete a waxy covering that totally surrounds their body with the exception of their piercing- sucking mouthparts. The voided, waxy, spherical covering of the insect is the most likely structure to be encountered. The sphere is pink to yellowish-brown in color and measures from 1/6 of an inch in diameter to as small as a grain of sand (Buss 2008). The exposed mouthparts are used to feed and attach to the roots of plants.
