Mystery bug
Mystery bug  

I am from the uk spotted this bug in a couple of kitchen cupboards. I have attached a picture I hope you can zoom in. It is black 6 legs the body is shape is inbetwern being round and oval. Also saw tiny pin point size white clear bugs running around. The black bug seemed to be attracted to wood although there are all manners of things in the cupboard. I cant figure out what it is can you please help me. Thank you.

Dear Saf - Your image is not clear enough for me to make a positive identification, but there are some possibilities:
(1) if the dark ones are relatively hard-bodied ('crunchies'), they might be one of the biscuit beetles, such as cigarette/drugstore beetles - see for an image.
(2) If they all (both the dark and the white ones) are relatively soft-bodied ('squishies'), they might be booklice - see
(3)  If the really tiny ones appear to move about in a seemingly random manner, they could be mites, such as flour mites - see for more information.

  If your city/municipality has an environmental section offering pest control services, you might consult them for advice - see for an example.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
