American Xyelid Sawfly
A minute primitive sawfly native to western North America with the family's characteristic elongated third antennal segment. Adults appear in early spring.
Did You Know?
Despite being among the most primitive Hymenoptera, xyelid sawflies are highly specialized in their larval diet, feeding exclusively on pine pollen.
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.
