And the other day in one of the poly tunnels two people saw another
small,
brown caterpillar exactly imitating a twig. As they touched it, it
sort of
reared up and took on another 'twig shape'.

A lot of the carpet moth caterpillars (and others) adopt that
defensive camouflage technique - usually the 'looper' caterpillars,
the ones with six little legs up front and only two pairs at the rear
end.

It's a pretty effective dodge, because they are not often seen.
