I sat on this thing, not having seen it on my office chair. It looks mean. Anyone know what it is?

Do you have a photo?

[Hedera]

??? Squashed!!!! Where is picture?

[sean6626]

yes, i do have a photo, but dont know how to get it on here.

try this:





Anyway, after a bit of research i worked out that the spike wasnt poisonous, and that it was on its bum, not its head.

think it might be a poplar hawk moth, but the biggest thing ive ever seen. almost had my eye out with that fang thing. Its still alive, i just missed it and put it out of the window.

It looks to me to be a Privet hawk moth larva. Hope you didn't kill it off It was probably going to pupate.

I would say Lime Hawk, horn not black as Privet would be, rough looking skin and yellowish patch on rear would suggest Lime Whatever it is, is not harmful, despite its wicked look..take it outside and place near trees (birch, lime, alder) and let it do its thing!
