Willard, J.R. 1973 Wandering time of the crawlers of California red scale, Aonidiella aurantii (Mask.) (Homoptera: Diaspididae), on citrus.. Australian Journal of Zoology. Melbourne 21: 217-229.

Notes: The distribution of times of emergence and settling ensures that most wandering occurs in the late morning when wind velocities are most favorable for dispersal.
