I am not sure if it is normal or not but I recently found a red-orange Pill Woodlice under some wood.
Please can somebody help me with why it is this unusual colour.
(length is 1cm,cannot roll into ball fully, found in Chandlers Ford)
The common pill woodlouse, Armadillidium vulgare can be the most common grey form or found in shades of pink, orange and brown. however, it does roll into a complete ball.
A. nasatum (the second most likely suspect - though the colouration isn't quite right) and A. depressum are other common pill woodlouse but they roll into incomplete balls, leaving a gap.
Your image looks like A. vulgare to me though!
Have you seen this excellent guide, A key to the Woodlice of Britain and Ireland by Stephen Hopkin - it's really good.
I am quite sure it was A. Depressum however as it never rolled into a complete ball their was a 4mm gap (approx.) I hope to post more threads about unusual critters soon.
Here is a cool picture as a thank you gift:
