It is possible that something (dog or other animal) pee'd on the asphalt, and the Tiger was responding to that.Chuck wrote: Fri Jun 13, 2025 4:03 pm An oddly interesting observation:
A "spring form" male was flying around looking for a place to puddle, on an old steel barge. He kept returning to what looked like a pile of racoon poop, but isn't- it's a random pile of 100 year old asphalt that looks like poo.
I wonder- are they using vision to find puddling resources? I always assumed that it's scent. That said, a puddle group attracts others, and that's clearly visual.
Butterflies clearly do use visual cues for many things too and they are often attracted to particular coloured objects. Once, in E Laos, I saw multiple butterflies investigating a discarded can, which was shiny pale blue.
