Aonidomytilus crookiae is a species of scale insect in the family Diaspididae which are often referred to as "armored scale insects." [1] It is commonly known as "St. John's Wort Scale." [2] Originally named Nelaspis crookiae by Gordon Floyd Ferris in 1954, [3] the taxon was moved to the genus Aonidomytilus in 1984 [4] as the result of a 1979 taxonomic revision of the genus. [5] Aonidomytilus multiglandulatus is a junior synonym. [1]
The scale of the female is approximately 1/10th of an inch (2.3mm) in length, oyster shell shaped, light brown in color turning yellowish white toward the apex, with orange yellow exuviae attached apically. [1] The body of the female insect under the scale is slender and spindle-shaped, with lobed ventral margins. [1] Their eggs are light purple in color. [1]
A. crookiae parasitizes plants in the genus Cistus in the rockrose family Cistaceae and the genus Hypericum in the family Hypericaceae including Hypericum microsepalum and H. prolificum. [6]
The species' geographic distribution includes the U.S. states Maryland, Virginia, Georgia, Florida, Alabama, Missouri, Illinois, Indiana, and Ohio, and probably adjacent states. [6]
