The image showcases three distinct views of lichens on an elm twig, each illuminated by a different light source: regular daylight and ultraviolet (UV-A) blacklight.

**Upper View**

* The top view presents the lichens under regular daylight.
* The lichens exhibit shades of green and yellow hues, with some displaying small orange dots.

**Lower View**

* In contrast, the lower view reveals the same lichens exposed to a 365 nm UV-A blacklight.
* This exposure causes the lichens to glow in vibrant colors:
   + Some appear red or pink
   + Others emit blue light
   + The orange dots from the previous image have turned bright yellow

**Overall Impression**

The image effectively highlights the unique properties of these lichens, which are capable of absorbing and emitting various wavelengths of light. – AI vision
