Chrysanthemum Flea Beetle

The chrysanthemum flea beetle (Psylliodes chrysocephalus) is a small leaf beetle in the family Chrysomelidae, native to Europe and western Asia. Adults are small, shiny, metallic bronze-green to blue-black beetles, and like other flea beetles, they possess enlarged hind femora that enable them to jump powerfully when disturbed, giving the group their common name. Both adults and larvae of this species feed on plants in the family Brassicaceae, particularly oilseed rape (Brassica napus), as well as members of related plant families. The specific association with chrysanthemum suggested by the common name may reflect occasional feeding on ornamental plants or historical misidentification, as the primary pest hosts in agricultural contexts are cruciferous crops. Adult beetles make characteristic small round holes in leaves, and larvae mine the stems of host plants. Psylliodes chrysocephalus is a notable agricultural pest of oilseed rape in parts of Europe, where larval stem mining can reduce crop vigor. Population levels are highest in autumn when adults are actively feeding and laying eggs. Integrated pest management strategies for flea beetle control include crop rotation, seed treatments, and biological controls.
