Last night I was sitting behind the house with some friends, when I heard a “plonk” where no plonk should be. I looked and found the biggest caterpillar I’d ever seen. It had crawled up a grass stalk but then gravity happened and it ended up on the terrace.
Turns out it’s the mature form of the Elephant Hawk Moth which are indeed about 8 cm (3″ and a bit) long. After taking the pictures I took the hapless traveller and put it some place with more green.
