Beetle released in 1969 to fight weeds now threatens 30+ native US plants
A European beetle introduced in the United States in 1969 to control invasive weeds has since become an ecological problem. Over time, the insect expanded its diet beyond its intended targets to feed on more than thirty native plant species, including rare thistles. The beetle's larvae damage plants by boring into flower heads and destroying seeds, severely disrupting reproduction. Smaller and more isolated native thistle populations have been hit hardest by this unintended impact. In response, US federal authorities have halted further releases of the beetle.
