Staphylinid beetle

 This tiny rove (staphylinid) beetle, about 5mm. long, found its way into the house, probably on washing dried on the washing line. But it might have flown in through an open window - the wings are tightly packaged under the wing cases, that look like a miniature back-pack, in the centre of the insect. These small staphylinids are weak fliers, generating enough lift to get airborne, but after that they’re at the mercy of wherever the wind and air currents take them.
