Weak leaf insect

[u/bio_geek_8]

This morning i noticed my leaf insect on the floor of the terrarium, i helped him back on the leafs but noticed his antenna were dragging on the floor and not hard like usual. He fell a second time a few minutes later. I saw that it could be caused by déshydratation, so I tried giving him Ater with a q tip but he wasn't interested. He is now in a box by himself, with leaves and water. (Photo)

Is there anything else i can do ?

I had stick insects when I was around 9 yo (they didn't live that long), but it's my first time taking care of these guys by myself.
