About a week ago a large lhm caterpillar was found on a concrete drive. It was put in box with some leaves (not lime). After a day or so it grasped a leaf stem and stopped moving. Then it shrunk quite a bit, and went very dark, and seems hard.
The box is left alone indoors, and reasonably moist.
Is it likely to be dead, or is this normal behaviour which may produce a moth? I know they can bury themselves etc and get on with it.

Does it look like a pupa (chrysalis)? If not it must be dead.

I guess so - it doesn't look like a dead caterpillar! It's very much gone from green to near black, though.

Maybe okay then. Have you got a photo?

Yes,, but I get:
"Unable to upload file CHRY1.jpg. Error: This forum has exceeded its attachment space limit. Your file cannot be uploaded. "
so what do I have to do? Try: <a href='https://postimg.cc/XZdSPC5x' target='_blank'><img src='https://i.postimg.cc/XZdSPC5x/CHRY1.jpg' border='0' alt='CHRY1'/></a>

That certainly is a pupa, so should be okay. Hopefully an adult moth will emerge, though sometimes what comes out is something different as many get parasitised so possibly parasitic wasps or flies emerge, but fingers crossed for the moth!

Not too many ichneumons or braconids in the kitchen, so they'd have had to have got into the caterpillar. Saw no eggs..
Anything I should do for the moth, apart from keep a damp tissue in the box?
Plenty of caterpillar poo in the box, btw, which I understand is a good sign because they empty themselves!

Still nothing. It's at least two weeks now. I fear the worst

It might be different if your pupa is in indoors and perhaps warmer than if outside but I thought Lime Hawk moths overwintered as pupae and emerged the following spring.

Hawk moths have just one brood, all except the poplar hawk moth which can have a second brood in which the caterpillars’ bury themselves about six inches into soil where they pupate normally emerging nine months later; including the first brood. In fact all hawk moths follow the same pattern, all except the Elephant hawk which just bury themselves into leaf litter. Incidentally, it doesn’t matter if the pupa is kept in the warm indoors or outside in the cold nine mouths remains the time period almost as if the pupa has a built in clock.

Ah, thanks Alan! Definitely not the poplar. It was the lime hawk caterpillar variant which has little red marks, wish I'd taken a photo. So, what should I do with the fellah, bury him ?
