A mealybug, Pseudococcus nr. microadonidum Beardsley (Homoptera: Pseudococcidae) has been found feeding on the foliage of E. joga. This mealybug was sometimes found in the domatia of yoga leaves. It has been recorded on coconut, banana, and pandanus from Kiribati, Pohnpei, and Marshall Islands. This insect is a new record on yoga and for Guam.
