My wife also found this Privet Hawk Moth
caterpillar (Sphinx ligustri) munching away in our garden. Apparently it's the biggest moth
we get here in the UK, the moths can have a wingspan of nearly 5 inches (about 12 cm). It was
hanging upside down on our privet hedge:
I think it was reasonably young, because I reckon it will get even bigger. It was great to find it
and be able to take a couple of photos.
