How to tell sick horn worms

[FortheLoveofLizzie]

Greetings,

Got a shipment of horn worms that stayed at postoffice one day and when I got them were huge! ( these guys grow fast so no surprise).

They also looked a bit moist.

I put them in basement with slightly lower Temps to slow them down but today really moist, moving and two had some black stuff on them...ugh

Sick feeling they may be dying

OR sick

Or transforming


Hints?

Feed?

When not to feed?

She ate one two days ago and seems fine. Just ate 60 phoenix worms now.

Thanks
