The LaMonte-Birds' Visitor

What kind of animal is it?
JinGi told us that it isn't an insect. We know it isn't an insect because it has legs (is this right?).

Is it dangerous? Can it bite? What does it eat?
Ho-jin:Bees can sting,and they eats honey,also they're dangerous.
praying mantis is dangerous because of front legs.
The visitor is kind of an centipede,and if you touch,a smell that you can not get it out easily,would be on your hand.

The toad can't eat that. Jiwoo Hey Jiwoo: What happens if it does? Does the toad die?
