I heard worms that eat tomato plants aren't safe. I'm not going off a "looks safe", sorry. I'm going to get it's exact name and know for sure it's safe.
Are you sure is not a tomato horn worm? It kinda looks like it but i cant realy tell from the pic. If it is then is not safe its toxic for chams but im sure you alrady know that.
Where did you find this from? It looks like a baby caterpillar of some sort.. If it is a worm that is so coool llol.. But I have no idea if it's safe...
I found a fat yellow one the the other day. But even tho it looked so yummy and my cham would kill to eat it i had to let it go. i couldnt identify it.
