Dung-loving Rove Beetle

A medium-sized, shiny black rove beetle with distinctly margined elytra found commonly in dung and compost. It is one of the most frequently encountered Philonthus species in pastoral landscapes.

💡

Did You Know?

This beetle has been introduced to New Zealand as a biological control agent against pastoral dung flies.

Ant Damsel Bug

A slender brown predatory bug whose nymphs remarkably mimic ants for protection from predators. Adults lose the ant-like appearance and become typical damsel bugs. It is a beneficial predator in European gardens and fields.

💡

Did You Know?

The young nymphs are such convincing ant mimics that they even walk with a jerky, ant-like gait, fooling both predators and entomologists at first glance.
