Wasp Twisted-Wing Parasite

An endoparasite of paper wasps where females spend their entire life inside the wasp host. Parasitized wasps are castrated and abandon their colony duties.

💡

Did You Know?

Female Xenos never leave their wasp host — they live, mate, and give birth to thousands of larvae while permanently embedded in the wasps abdomen.

Tachydromia Dance Fly

A tiny wingless dance fly that runs rapidly over tree bark hunting for small arthropods. Despite being flightless, it is an agile predator of mites and springtails on trunk surfaces.

💡

Did You Know?

It is one of the few completely wingless flies, sprinting across tree bark at high speed to catch tiny prey.
