1. Spiderlings of the crab spider Misumena vatia and nymphs of the ambush bug Phymata americana normally ambush prey in flowers, as do the adults. The immatures of M. vatia are more mobile, by ballooning, than the ambulatory but largely sedentary adu

Two colour morphs of Enoplognatha ovata (Clerck), “redimita” and “lineata” the abdomens of which are whitish with two pink stripes and greyish-yellow, respectively, differ in their foraging strategies. When placed in artificial arenas with fl

The foraging behaviour of honey bees (Apis melliferaL.) on inflorescences of staghorn sumac [Rhus hirtaSudworth (ex-typhinaL.)] was studied using a “choice table” placed in natural stands of this plant. The choice table consisted of a wooden grid

Optimal foraging theory predicts that foragers with an imperfect knowledge of the environment will invest time sampling the foraging area. The ambush bug Phymata americana Melin appertains to this category of foragers because it has shown, in previou

Field-collected individuals of Misumena vatia and Phymata americana were compared experimentally as to the kind of vegetation and flower cues they use to choose a hunting site, by introducing them into choice arenas with variously manipulated natural

When considered together, the diversity and abundance of biologically similar organisms (e.g. pollinators) within a community, are more powerful in assessing the effects of disruption than when taken separately. The log-normal model of abundance and
