Went out for a walk around the school building in the afternoon and I saw a giant water bug (Family Belostomatidae) crossing the parking lot. I picked it up (while avoiding its proboscis) and decided to bring it home to get a photo of it.
While in my room, it started flying towards the light. Feeling bad for it (and being kind of nervous of a large-sized insect with a nasty bite flying around in my room), I let it go right after. Very cool encounter though.
