Armadillidium vulgare or pictum pill woodlouse

Woodlouse in shape and size and behaviour but deep chocolate brown instead of common grey. I didn't poke it to see if it would roll up.

I didn't know there was such a thing as a pill millipede. Love the question about how many legs it had!

So do they both roll up then? Have I been calling millipedes woodlice for over 40 years?!!

Yes they do roll up but looks

Yes they do roll up but looks less spherical. My opinion : The millipede is seen less often (though not uncommon in the south) and prefers shade whereas the woodlouse species (Armadillidium) is not afraid to wander about in the sun - lots of them about now.

I shall have to look more closely in future - when I looked on Wikipedia I realised I had noticed some of the differences, just hadn't really thought about them. I used to love 'farming' woodlice as a child!

Pill woodlouse or millipede

Oh dear, I must improve my observations. I do not know how many legs it had. It looked so busy I didn't like to interrupt it. The sighting was on the margin of mature mixed woodland. Lots of leaf litter etc
