Identify this insect

[skier-hughes]

Hi All, can anyone identify these?
They are around 15mm long 3mm wide and have been coming through my friends sons ceiling last night and again this morning.
They are in a very straight line about an inch or so from a beam.
Holes are about 3/4mm dia.
Don't know what the ceiling is made from yet, could be plasterboard, could be lath and plaster.
House is 200 years old, stone cottage, terraced, in Yeadon North Yorks about 50m from a tarn.
Don't know what is above the ceiling yet.

No idea myself, but, I may know a man who can. I've sent him a copy of the photo but it may take a while to get a reply, he's fossil hunting in China at the moment.

I'm still waiting for confirmation from my pal in China but provisionally these may be Plaster Beetles.

They are attracted to and live in damp and slightly cool locations in the house and can attack both old and new properties. Theres plenty of data on the net about them but intervention will be required to kill off the colony and prevent future infestation.

I'll let you know if said mate in China comes back with anything different.

Thanks, Matt Green has told me he believes them to be a fly type insect, so to investigate the loft. I'm awaiting news on what has been found in the loft, if anything and am googling your idea.
