Lacewing larva ... in disguise ?

Spotted this on some ivy whilst walking up Longwood Drive, near Coryton, this afternoon. At first I thought it was a bit of detritus on the leaf, about the size of a small ladybird, then it moved and I saw the legs. 'Twas a bit breezy but I managed a couple of grab shots before it disappeared. The legs and mandibles can be seen in the first image and the back end of the abdomen in the second. Only thing I can find that looks remotely like this is a lacewing larva  ..... any advance on that?
