Parasitic Acacia Ant
A cheater species that occupies acacia thorns but provides little defensive benefit to the host tree. Unlike mutualist acacia ants, it does not attack herbivores or clear competing vegetation.
Did You Know?
It exploits the mutualism by taking food from the acacia without reciprocating with defense, essentially freeloading.
Jack Pine Sawfly
A serious defoliator of jack pine in the Great Lakes region. Periodic outbreaks can strip thousands of hectares of jack pine.
Did You Know?
Outbreaks are often triggered by several consecutive years of warm, dry spring weather.
