Bipunctate Aleocharine
A robust aleocharine rove beetle with two reddish spots on its elytra, serving as both predator and parasitoid of agricultural pest flies. It is one of the best-studied biocontrol staphylinids.
Did You Know?
This beetle has a dual attack strategy: adults eat pest fly eggs on the surface while their larvae burrow into the soil to parasitize fly pupae underground.
Giant Robber Fly
A large, bristly predatory fly with powerful grasping legs and a sharp proboscis. It ambushes prey in mid-air with remarkable speed and precision, including insects larger than itself.
Did You Know?
Robber flies inject prey with saliva containing neurotoxins and digestive enzymes, liquefying the insides and then sucking them out.
