To assess the potential for social learning in bumblebees (

Over the past three decades, a significant body of research has identified declines in bumble bee (
Bombus) faunas of several European nations (Williams, 1982; Sarospataki et al., 2005; Goulson et al., 2006; Fitzpatrick et al., 2007; Kosior et al., 2007; Williams and Osborne, 2009).
