Purple Loosestrife Beetle
A small, yellowish-brown beetle deliberately introduced as a biocontrol agent against invasive purple loosestrife. Adults and larvae feed on leaves and growing tips of the target weed.
Did You Know?
This beetle has been one of the most successful classical biological control agents, dramatically reducing purple loosestrife infestations across North America.
