I found it in a conifer in my garden that is proving to be something of a magnet for ladybirds this year. There are literally dozens of Seven Spot Ladybirds in it as well as a few Pine Ladybirds and the occasional Harlequin. And now a Larch Ladybird.
It's much smaller than the Seven Spot Ladybird, only around 4mm in length, and not as glamorous either but it's still welcome in my garden.

it's characteristic marking is the W shape on its pronotum (the pale area above its eyes)
