Chagasi Sandfly
A small sandfly found in northern Colombia and Venezuela that is an important vector of Leishmania infantum chagasi, causing visceral leishmaniasis in the Americas. It thrives in peridomestic environments and feeds on dogs, the main reservoir host, as well as humans.
Did You Know?
Insecticide-treated dog collars have been used to reduce visceral leishmaniasis transmission by this species by protecting the canine reservoir.
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.
