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.
