Sorry, should have said. It it barely 5 mm. It's tiny.

it looks to me to be in the lady bird family so is a predetore and good for your garden but I don't know its actual name .

Larch Ladybird - Aphidecta obliterata. See http://www.naturespot.org.uk/species/larch-ladybird

Larch ladybird it is. Thank you. Glad I didn't squish it. Wonder what woke it up? (Central heating maybe up too high). :-)

not a bad guess even if I say so myself . im not intirely stupid lol . never seen one before .
