Recent records of Nathrius brevipennis (Mulsant) (Cerambycidae) in London

摘要

On 18 July 2010 I found a specimen of this curious little beetle, crawling on my arm, as I read the newspaper at the end of my garden (TQ343743, VC 17 Surrey). It took a few moments before I realized what it was. Actually, it took a few moments before I realized it was a beetle. Its size, speed and agile gait made me first think it was an ant. Then, its lack of geniculate antennae made me think it might be one of the small wingless ichneumons. Luckily I was doing the crossword, so had my reading glasses on, and a final close focus brought the realization that it was Nathrius.
