Well I found 3 of these babies happily munching away in my garden this morning! They are about 10cm long, as fat as my thumb and have a little yellow tail. I’d like to know what they are, if they’re particularly common and also how long I will have to wait before they stop demolishing my plants!
We would love to identify your caterpillar, but without global coordinates, we don’t know where to start looking for an exact Sphinx Moth species from the 1000’s of possibilities. The name of the food plant would also help.
Apologies at not mentioning I’m in Bangkok, Thailand…it must have been over excitement at having dinosaur like caterpillars in my garden! I’ve narrowed down the shrub they’re eating to some kind of Gardenia, maybe ‘Cape’. I hope this helps.
We did locate a website of the Hawk Moths of Thailand, but there are no caterpillar photos.
