Following the first Stigmus pendulus ^[1] nest in the Butterfly bush, the site has evolved in two seasons into a colony with at least more then five nesting females. Fortunately the beetles producing the 2 to 3 millimeter large drill holes increased in number as well so many new potential nest locations are available that can be shared with the competition, especially Passaloecus and to a lesser extent Crossocerus.

The female in the photo is occupied with extensive cleaning of a drill hole prior to use.
