Japanese Soldier Fly

A slender soldier fly with a metallic greenish-black body and elongate antennae. It is commonly found near decaying organic matter in gardens and forests across East Asia.

💡

Did You Know?

Like the black soldier fly, species of Ptecticus are being studied as potential bioconversion agents for organic waste.

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.
