Entomology (Study of Bugs)/Mystery Bug



Hi Ed,
I found this bug crawling on my bed. I'm thinking maybe it fell from the ceiling on my sheets. I immediately looked around the mattresses for bed bugs and nothing. I may have cracked him when I picked him off my bed. I dropped him in a glass of water since I didn't know if he could fly or jump. I am a little skittish with Bugs.
Please see attached. Thank you so much

Dear Patricia - I cannot be certain from your images, but this small beetle (definitely not a bed bug!) could be a black carpet beetle (Attagenus unicolor; Coleoptera: Dermestidae) or close relative. See ttp://tinyurl.com/pvgfq3 for a fact sheet that includes control recommendations.
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.
