I've noticed something interesting that I cant get an answer to online. Whenever I leave out watermelon in my house (After eating it of course. I cut slices from the melon so what gets left behind is the rind), it attracts lots of gnats and flies without failure. After cutting and eating a Yellow Watermelon for the first time and then leaving it out, There wasn't a single fly that cared for it, it was never swarmed or landed on or fed upon. it just sat there for a day or so before I finally threw it out.

Why is this?? Repeating this same scenario always gives me the same output. The flies aren't attracted to the Yellow Melon, Why?

I've read that red variants of veggies like cabbage get less attacked by caterpillars, and anecdotally, it seems to be true. It makes sense that insects would be evolved to target the more "natural" color.
