This work shows that Leptothorax albipennis ants can lower their quorum thresholds between benign and harsh conditions to adjust their speed–accuracy trade–off, and that in harsh conditions these ants rely much more on individual decision making than collective decision making.
Ecology: A Prerequisite for Malaria Elimination and Eradication
It is argued that malaria eradication efforts will not be successful until a better understanding of the ecology and evolution of the mosquito vectors is gained.
Psychophysics: Bees trade off foraging speed for accuracy
Bees are the first example of an insect to show between-individual and within-individual speed– accuracy trade-offs, and each bee will sacrifice speed in favour of accuracy when errors are penalized.
Behavioural syndromes and social insects: personality at multiple levels

The goal of this review is to illustrate the ways in which both the study of social insects and of behavioural syndromes has overlapped, and to highlight ways inWhich both fields can move forward through the synergy of knowledge from each.
Temporal dynamics and network analysis
An overview of time-ordered networks is presented, which provide a framework for analysing network dynamics that addresses multiple inferential issues and permits novel types of temporally informed network analyses.
Benefits of recruitment in honey bees: effects of ecology and colony size in an individual-based model
An individual-based model of honey bee foraging was developed to quantify the benefits of recruitment under different spatial distributions of nondepleting resource patches and with different colony sizes, finding that benefits were strongly dependent on resource patch quality, density, and variability.
Why do not all workers work? Colony size and workload during emigrations in the ant Temnothorax albipennis

The results suggest that small colonies may be extremely dependent on a few key individuals, and the amount of work performed by each individual, not just task repertoire (which tasks are performed at all), should be taken into account.
Why do honey bees dance?
It is found that the clustering of bee forage sites in a variety of habitats by evaluating the bees’ dances is more clustered in tropical than in temperate habitats, which supports the hypothesis that in the context of foraging, the dance language is an adaptation to the particular habitats in which the honey bees evolved.
Food alert in bumblebees (Bombus terrestris): possible mechanisms and evolutionary implications
This work investigates the mechanisms by which the return of a successful bumblebee forager stimulates nestmates to leave the nest and search for food, and the implications of bumble bee recruitment behavior for the evolution of communication in bees are discussed.
Insect behaviour: Evolutionary origins of bee dances
New light is shed on the early evolutionary origins of the elaborate dance language of the honeybee by showing that bumble-bee communication uses a primitive, but surprisingly efficient, recruitment system.
