Thank you, glad you like my work!

No, fluorescent UV imaging is inducing visible light be using UV as a stimulus. My work is REFLECTED UV, i.e. invisible UV light is being photographed (2nd image) using a modified camera but the colors you see are false colors (like NASA uses for their imaging). The simulated Bee and butterfly imaging uses UV + visible light, but also is partly false color imaging, as colors are mapped into our (limited) human color range.
