operation of the alula as an indicator of gear change in hoverflies.	the alula is a hinged flap found at the base of the wings of most brachyceran diptera. the alula accounts for up to 10 per cent of the total wing area in hoverflies (syrphidae), and its hinged arrangement allows the wings to be swept back over the thorax and abdomen at rest. the alula is actuated via the third axillary sclerite, which is a component of the wing hinge that is involved in wing retraction and control. the third axillary sclerite has also been implicated in the gear change mechanism ...	2012	22072452
behavioural mimicry of honeybees (apis mellifera) by droneflies (diptera: syrphidae: eristalis spp.).	droneflies (syrphidae: eristalis spp. resemble honeybees (apis mellifera) in appearance and have often been considered to be batesian mimics. this study used a focal watch technique in order to compare the foraging behaviour of droneflies eristalis tenax, eristalis pertinax, eristalis arbustorum and eristalis nemorum) whilst they were feeding on patches of flowers with the behaviour of honeybees and other hymenopterans and dipterans. it was found that, on a range of plant species, the time drone ...	2000	10853733
