New research led by scientists at Penn State reveals how the daily cycles of plant aromas are linked to the dietary habits and evolution of the winged insects collectively known as Lepidoptera .

Salient Aroma Hypothesis suggests the smells plants release play a crucial role in determining how specialized a butterfly or moth's diet becomes.

Insect herbivores, such as butterflies and moths, must find the right plants to feed on and lay their eggs.

The Salient Aroma Hypothesis helps explain why some insects are highly specialized while others are more flexible in their diet.

On the other hand, night -active species, like the Polyphemus Moth , encounter fewer and less diverse plant aromas.
