Alpine Longhorn Beetle

A strikingly beautiful blue-grey beetle with black spots, listed on multiple European conservation directives. Depends on old-growth beech forests with standing dead wood.

💡

Did You Know?

This beetle is so dependent on ancient beech forests that a single dead tree can support an isolated population for decades — but when that tree is gone, so is the colony.

Banana Stalk Fly

A slender long-legged fly from Australia whose body size depends on larval nutrition. Larger males pass on a size advantage to offspring even through a non-genetic pathway.

💡

Did You Know?

Research on this species demonstrated transgenerational effects where paternal diet quality affected offspring body size without changes to DNA.
