Hi. Please could you give me some help identifying this beetle. I find a few now and then dead and alive on the window sills and sometimes on the walls upstairs and downstairs in my house. I live in Newcastle upon Tyne. I'm a bit worried it might be woodworm beetles, although I've had a good look in the roof, down the back of a skirting board that's popped off and under the floor of one of the bedrooms upstairs when we were decorating, and under the stairs and found no signs of woodworm holes. I don't think it's from any of the furniture as we moved house last October and I don't remember seeing them at our old flat.
It's about 3-4 mm long I think and dark brown. They are quite easy to catch as they don't seem to make any effort to fly away - I've never seen any flying. I've attached some pictures, although they are all pretty small. The pen marks are 5mm apart.
Thanks for your help,
It was difficult to see the detail from your picture, but try some searches on biscuit beetle. Also called a drugstore beetle. The details on wikipedia (below) will help you to see if this fits. Lots of council websites have advice on how to deal with them if this picture looks like your critter. Best wishes Birdwocha
Definetly a deathwathch beetle. if they are you might hear them tapping their heads against the wall. I'm no expert so I might be wrong. They might be drugstore beetles as well.
Try checking it out yourself.
We may be able help you identify this if you post better pictures. You could also try to send us a dry dead specimen:
Identification and Advisory Service
Angela Marmont Centre for UK Biodiversity
The Natural History Museum
Cromwell Road, London
SW7 5BD, U.K.
Please put it in some rigid container that would protect it from crushing and also fit into an envelope. Could be a matchbox, a small plastic tube, etc.
If you want it returned after we ID it, please let us know.
Thank you for posting this.
I looked up woodworm and deathwatch beetles. The deathwatch beetle is about 7mm long which is probably too big for yours, and the shape doesn't look quite right. Lets hope it isn't a deathwatch beetle, because apparently they are often associated with dry rot! The one in your picture seems about the right size for a woodworm beetle; but looks a bit too "fat" to me. If you are in the UK it also seems rather early for woodworm (i.e. the common furniture beetle, Anobium punctatum), unless the recent warm weather has brought them out. They are supposed to emerge from about May.
Best to send a specimen for identification as suggested - it seems impossible to be certain otherwise.
I have found these insects behaving just as Catherine describes. They are found on window sills and walking slowly up windows. They appear black but from the image I've attached have markings on the wing casings. They first appeared in July and are still here in August. I'm in rural Cornwall. Would this image help anybody establish a more definite identification? Thanks
Anthrenus is much rounder. And note the downturned head which is typical for a bark beetle. I agree with Bombuslucorum that it is a Hylesinus (=Leperisinus) fraxini (=varius?). See http://www.kerbtier.de/Pages/Fotos/FotoLargeN/Scolytidae/Leperisinus-fraxini-n.jpg.
I know this is an old link but nobody seems to have made a correct identification. I am new to the site but recognised this bug instantly. I think it is a Carpet Beetle as I know it. A quick check tells me a Varied Carpet Beetle. As I remember them they look almost velvety on the wing cases. Hope that helps everyone interested.

Did you say Carpet Beetle? Certainly not. Please compare with these images:
Hylesinus varius is much more likely:
ummm i'm not sure, but. can anyone tell me what this beetle is?
In Sweden we have two species of Melolontha, M. melolontha and M. hippocastani (the latter is commoner and more widespread in Sweden - it is more connected to the forests and poorer soils futher north from where reasonble people, like me, live). The easiest way to tell them apart is that M. hippocastani has the foremost half of the outer edge of the elytra black (turn the beetle upside-down!), while it is all brown in M. melolontha. There is also a difference in the shape of the pygidium (the posterior shield-like part of the abdomen (more "straight-edged" triangular and stouter in M. melolontha). There is a third species in more southern parts of Europe (and I don't know if you have it in Britain), M. pectoralis, with whom I'm not familiar.
Lots of 'noise' here; the Hylesinus scolytidae was correct, but that is not the same as the original picture; the original picture (which is not very good) can be either the biscuit beetle or the death watch beetle (both Anobiidae); the former feeds on flour/ biscuits/ dog food etc. and the latter on oak beams. Death watch is almost twice the size of biscuit beetle, and with a different pattern (not visible here)
