“…Route following by honeybees meets several key features of trapline foraging previously described in bumblebees and some other nectar-feeding insects, birds and mammals (Janzen, 1971;Lihoreau et al, 2010Lihoreau et al, , 2012Ohashi et al, 2007;Tello-Ramos et al, 2015): (1) honeybees used flower visitation sequences that became increasingly similar with training, ultimately stabilising into a single route (Lihoreau et al, 2012); (2) route establishment was accompanied by a reduction of revisits to empty flowers (Ohashi et al, 2007) and overall travel distances (Lihoreau et al, 2010); and (3) route optimisation was more pronounced at larger spatial scales (Lihoreau et al, 2012). Presumably, the energetic costs of flying long (suboptimal) routes in the large-scale array increased the investment of foragers in route learning.…”

“…Trapline foraging may efficiently complement cooperative foraging to exploit resources in the vicinity of the hive (where dance recruitment does not occur) or in environments in which resources are less clumped or not large enough to sustain multiple foragers at once (early or late in the season). In contrast to dance communication (Dornhaus and Chittka, 1999), the ability to rely on individual memory to search and exploit foods is observed in a large diversity of bee species (Janzen, 1971;Lihoreau et al, 2010Lihoreau et al, , 2012Ohashi et al, 2007), including the most socially advanced, suggesting that trapline foraging is ancestrally shared in this insect group.…”

“…These include noting regular appearances of individuals at fixed resource sites v www.esajournals.org (Janzen 1971) or the drawing of schematic flight maps tracing bee pathways (Heinrich 1976, Thomson et al 1982. The use of more rigorous quantitative statistical tools to identify traplining behavior only began in the last two decades (e.g., Thomson et al 1997, Ohashi et al 2007, Ohashi et al 2008.…”
