Mealybugs are insects in the family Pseudococcidae, unarmored scale insects found in moist, warm climates.

Fossil specimens of genus Acropyga have been found in Dominican amber carrying the extinct mealybug genus Electromyrmococcus (Johnson et al., 2001). These fossils represent the oldest record of the symbiosis between mealybugs and Acropyga species.
