Question
Bug
Bug  
Hi There,
I've found a couple of these bugs in my office and was wondering what they are? They are very small, like the size of a little black ant. Thank you!

Answer
Dear Alyssa - This looks like one of the silvanid grain beetles in the genus Oryzaephilus, either a saw-toothed grain beetle (O. surinamensis) or a merchant grain beetle (O. mercator). These beetles will infest a variety of dry stored food products such as flour, baking mixes, dry cereals, nut meats, dried fruit, etc. See <http://tinyurl.com/oyejdhx> for more detailed information, including control recommendations.

Hope this helps,
Saugy

Expertise

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.

Experience

21 years in the U.S. Army as a medical entomologist; duties varied from surveillance of pest populations (including mosquitoes, cockroaches, ticks, and stored products pests) to conducting research on mosquito-virus ecological relationships and mosquito faunal studies. Ten years as a civilian analyst for the Department of Defense, primarily on distribution of vector-borne diseases worldwide. Limited experience on surveillance of agricultural insects in North Dakota and Indiana.
