Saperda candida
Round-headed Apple Tree Borer
Saperda candida is a longhorned beetle (Cerambycidae) native to North America. It is a significant pest of trees in the rose family (Rosaceae), particularly apple, pear, hawthorn, and crabapple. The species was described by Fabricius in 1787 and occurs across Canada and the eastern United States. Its larvae are roundheaded borers that tunnel beneath bark and destroy cambium tissue, often killing young or stressed trees.
