A rather sleepy hornet who had been shut in a house for a week.
You can tell it is a hornet firstly by its size, but also because its thorax is totally brown.
A goat moth caterpillar (Cossus cossus) – so called because of its smell.
This gives a better idea of its size. A goat moth feeds on the wood of various deciduous trees only emerging after about 4 years when they change to a pupa.
