Self-heal (Prunella grandiflora).
Pic 1: Pollen illuminated iwth UV light.
Pic 2: without UV light, for comparison.
Pollen often shows fluorescence, often in the bluish range, due to phenylpropanoids (e.g. ferula acid).
The photo was taken with a longpass filter, tonenhance the contrast and to remove reflected blue light from the UV light source.

So maybe insects see these kinda fluorescent since they see wavelengths of light we can’t see
