European Oil Bee

One of only two Northern Hemisphere bees that collect floral oils instead of nectar as a food provision. It collects oils from yellow loosestrife flowers.

💡

Did You Know?

It mixes collected floral oil with pollen to create a waterproof, long-lasting larval food that resists mold in its damp underground nests.

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.
