Hornets’ nest

Hornets' nest

Section of a hornet’s nest with grubs still in occupation

‘Mad as a hornet.’  ‘Stirring up a hornets’ nest.’

Hornets are an insect with a fearsome reputation.

But when I squirted this nest with a specialist spray there was scarcely any reaction.

Luckily for me.

What I found afterwards was a structure of extraordinary artistry occupied by some pathetic (if gross) little grubs.

I’m glad idioms aren’t always right.
