Diva butterfly crashes baby koala's photo shoot

This baby koala is cute. But a passing monarch butterfly thinks it's even cuter.

Willow, a cuddly young resident at Symbio Wildlife Park south of Sydney, was posing for a recent photo shoot when she was interrupted by the butterfly.

The diva insect posed on Willow's forehead and nose, gracefully flexing its wings and totally upstaging the marsupial.

The adorable video has been watched more than 2.8 million times on Symbio's Facebook page.
