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.

Onion Thrips

A cosmopolitan pest of onions, garlic, and many other crops. It can reproduce both sexually and parthenogenetically and transmits iris yellow spot virus.

💡

Did You Know?

Onion thrips can reproduce without mating through parthenogenesis, allowing a single female to establish an entire infestation.
