The mexican lac scale Tachardiella mexicana (Comstock) (Hemiptera: Kerriidae) (EENY552/IN990)

Figure 1. Adult female tests of Tachardiella mexicana on wax myrtle.The Mexican lac scale is native to Mexico and Texas, but populations have been established in Florida. Adult female scales produce a high-domed ‘test’ or shell with four to six lobe-like projections that anchor the test to the plant surface. The test is hard and glossy with a reddish-orange tint around the edges, and darker toward the center. In some specimens, white string-like wax fiber extrusions project from the dorsum of the test, but these may break off. This 3-page fact sheet was written by Ian Stocks, and published by the UF Department of Entomology and Nematology, April 2013.
