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.

Two-lined Chestnut Borer Leaf Beetle

A convex beetle with metallic dark greenish-black elytra and fine punctation. It is found on alder and willow in boreal forests across northern North America.
