I made a huge LED display using lifx tiles (which are no longer sold). 5x5 tiles in a square, so I could hack video rendering and images to the lights. Each tile had 64 LED bulbs which could be independently controlled, both in brightness and colour.

When I did this I was in the countryside and I can state without hesitation that the insects loved it and flocked to it and while I found it cute, it was annoying because they would occasionally get trapped in the small gaps between the tiles and get stuck.

I'm therefore 100% convinced that insects just love fancy lighting setups.
