Found this little guy walking on my pants—who is he, and why is he like this?

So, I found this little guy casually strolling on my pants, and honestly, I was scared shitless at first. I moved him to the table, and he started exploring the objects there like he was on a mission.

Thinking he might fly away, I placed him on the windowpane, but nope-he's still hanging out. He doesn't seem to want to leave. I decided to dab some sugar water on a cotton pad to see if he'd like it, and he definitely does.

I have no idea what kind of creature he is or why he's behaving this way. Is he okay?Should I be doing anything else to help him?Any insights?

Here's a picture of him, in case it helps
