Peter Parker did that 

Spiders will often build webs around bright lights if they can tell it's attracting bugs. I wonder if the infrared light from the camera is in the visible spectrum for the spider...just something to think about.

I'm pretty sure one crawled on my leg and I swatted it away after freaking out. It could have been loose fabric, I didn't see it land but I did see a spindly think of black. I'll assume it was le spider. 

That’s one of the spiders that dies on site. 

Not an ichthyologist, but I will not allow any animals to be harmed! 

Rachnea for best gurl!

@Windows7ge The led's spectrum is large enough where some of the visible red bleeds in.
So you can actually see the led's.  Very dark red.

My guess is that the led's generate a good amount of heat.

I would assume that a cold blooded creature would appreciate that.

I'm aware that we can see it just a tiny bit but I'm wondering if spiders can see it significantly more. Alternatively heat would be another good reason for it to want to hug the camera.

@Windows7ge From the minimal research that I did, spiders can see ultraviolet light, but not infrared.

Neither does flys, or other insects that spiders commonly eat.

So my guess is either the warmth, or the cameras make a good wind break, due to them having a plastic shade over them.

Or both.
