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.
Australian Horned Dung Beetle
A small brown tunneling dung beetle native to Australia with minor horns in males. It was one of the first dung beetle species studied in early Australian biological control programs. It excavates tunnels beneath cow pats.
Did You Know?
Australia imported dozens of dung beetle species to deal with cattle dung that native beetles could not process.
